Description
Larry graduated this year and finally has a job. He's making a lot of money, but somehow never seems to have enough. Larry has decided that he needs to grab hold of his financial portfolio and solve his financing problems. The first step is to figure out what's been going on with his money. Larry has his bank account statements and wants to see how much money he has. Help Larry by writing a program to take his closing balance from each of the past twelve months and calculate his average account balance.
Input
The input will be twelve lines. Each line will contain the closing balance of his bank account for a particular month. Each number will be positive and displayed to the penny. No dollar sign will be included.
Output
The output will be a single number, the average (mean) of the closing balances for the twelve months. It will be rounded to the nearest penny, preceded immediately by a dollar sign, and followed by the end-of-line. There will be no other spaces or characters in the output.

Description
Problems involving the computation of exact values of very large magnitude and precision are common. For example, the computation of the national debt is a taxing experience for many computer systems.
This problem requires that you write a program to compute the exact value of Rn where R is a real number ( 0.0 < R < 99.999 ) and n is an integer such that 0 < n <= 25.
Input
The input will consist of a set of pairs of values for R and n. The R value will occupy columns 1 through 6, and the n value will be in columns 8 and 9.
Output
The output will consist of one line for each line of input giving the exact value of R^n. Leading zeros should be suppressed in the output. Insignificant trailing zeros must not be printed. Don't print the decimal point if the result is an integer.

Description
Businesses like to have memorable telephone numbers. One way to make a telephone number memorable is to have it spell a memorable word or phrase. For example, you can call the University of Waterloo by dialing the memorable TUT-GLOP. Sometimes only part of the number is used to spell a word. When you get back to your hotel tonight you can order a pizza from Gino's by dialing 310-GINO. Another way to make a telephone number memorable is to group the digits in a memorable way. You could order your pizza from Pizza Hut by calling their ``three tens'' number 3-10-10-10.
The standard form of a telephone number is seven decimal digits with a hyphen between the third and fourth digits (e.g. 888-1200). The keypad of a phone supplies the mapping of letters to numbers, as follows:
A, B, and C map to 2
D, E, and F map to 3
G, H, and I map to 4
J, K, and L map to 5
M, N, and O map to 6
P, R, and S map to 7
T, U, and V map to 8
W, X, and Y map to 9
There is no mapping for Q or Z. Hyphens are not dialed, and can be added and removed as necessary. The standard form of TUT-GLOP is 888-4567, the standard form of 310-GINO is
310-4466, and the standard form of 3-10-10-10 is 310-1010.
Two telephone numbers are equivalent if they have the same standard form. (They dial the same number.)
Your company is compiling a directory of telephone numbers from local businesses. As part of the quality control process you want to check that no two (or more) businesses in the directory have the same telephone number.
Input
The input will consist of one case. The first line of the input specifies the number of telephone numbers in the directory (up to 100,000) as a positive integer alone on the line. The remaining lines list the telephone numbers in the directory, with each number alone on a line. Each telephone number consists of a string composed of decimal digits, uppercase letters (excluding Q and Z) and hyphens. Exactly seven of the characters in the string will be digits or letters.
Output
Generate a line of output for each telephone number that appears more than once in any form. The line should give the telephone number in standard form, followed by a space, followed by the number of times the telephone number appears in the directory. Arrange the output lines by telephone number in ascending lexicographical order. If there are no duplicates in the input print the line:
No duplicates.

Description
How far can you make a stack of cards overhang a table? If you have one card, you can create a maximum overhang of half a card length. (We're assuming that the cards must be perpendicular to the table.) With two cards you can make the top card overhang the bottom one by half a card length, and the bottom one overhang the table by a third of a card length, for a total maximum overhang of 1/2 + 1/3 = 5/6 card lengths. In general you can make n cards overhang by 1/2 + 1/3 + 1/4 + ... + 1/(n + 1) card lengths, where the top card overhangs the second by 1/2, the second overhangs tha third by 1/3, the third overhangs the fourth by 1/4, etc., and the bottom card overhangs the table by 1/(n + 1). This is illustrated in the figure below.
Input
The input consists of one or more test cases, followed by a line containing the number 0.00 that signals the end of the input. Each test case is a single line containing a positive floating-point number c whose value is at least 0.01 and at most 5.20; c will contain exactly three digits. Output
For each test case, output the minimum number of cards necessary to achieve an overhang of at least c card lengths. Use the exact output format shown in the examples.

Total Submissions:74768 Accepted:22336 Description
Some people believe that there are three cycles in a person's life that start the day he or she is born. These three cycles are the physical, emotional, and intellectual cycles, and they have periods of lengths 23, 28, and 33 days, respectively. There is one peak in each period of a cycle. At the peak of a cycle, a person performs at his or her best in the corresponding field (physical, emotional or mental). For example, if it is the mental curve, thought processes will be sharper and concentration will be easier. Since the three cycles have different periods, the peaks of the three cycles generally occur at different times. We would like to determine when a triple peak occurs (the peaks of all three cycles occur in the same day) for any person. For each cycle, you will be given the number of days from the beginning of the current year at which one of its peaks (not necessarily the first) occurs. You will also be given a date expressed as the number of days from the beginning of the current year. You task is to determine the number of days from the given date to the next triple peak. The given date is not counted. For example, if the given date is 10 and the next triple peak occurs on day 12, the answer is 2, not 3. If a triple peak occurs on the given date, you should give the number of days to the next occurrence of a triple peak.
Input
You will be given a number of cases. The input for each case consists of one line of four integers p, e, i, and d. The values p, e, and i are the number of days from the beginning of the current year at which the physical, emotional, and intellectual cycles peak, respectively. The value d is the given date and may be smaller than any of p, e, or i. All values are non-negative and at most 365, and you may assume that a triple peak will occur within 21252 days of the given date. The end of input is indicated by
a line in which p = e = i = d = -1.
Output
For each test case, print the case number followed by a message indicating the number of days to the next triple peak, in the form:
Case 1: the next triple peak occurs in 1234 days.
Use the plural form ``days'' even if the answer is 1.

DNA Sorting
Time Limit: 1000MS Memory Limit: 10000K
Total Submissions: 51759 Accepted: 20218
Description
One measure of ``unsortedness'' in a sequence is the number of pairs of entries that are out of order with respect to each other. For instance, in the letter sequence ``DAABEC'', this measure is 5, since D is greater than four letters to its right and E is greater than one letter to its right. This measure is called the number of inversions in the sequence. The sequence ``AACEDGG'' has only one inversion (E and D)---it is nearly sorted---while the sequence ``ZWQM'' has 6 inversions (it is as unsorted as can be---exactly the reverse of sorted).
You are responsible for cataloguing a sequence of DNA strings (sequences containing only the four letters A, C, G, and T). However, you want to catalog them, not in alphabetical order, but
rather in order of ``sortedness'', from ``most sorted'' to ``least sorted''. All the strings are of the same length.
Input
The first line contains two integers: a positive integer n (0 < n <= 50) giving the length of the strings; and a positive integer m (0 < m <= 100) giving the number of strings. These are followed by m lines, each containing a string of length n.
Output
Output the list of input strings, arranged from ``most sorted'' to ``least sorted''. Since two strings can be equally sorted, then output them according to the orginal order.

Maya Calendar
Time Limit: 1000MS Memory Limit: 10000K
Total Submissions: 43005 Accepted: 13131
Description
During his last sabbatical, professor M. A. Ya made a surprising discovery about the old Maya calendar. From an old knotted message, professor discovered that the Maya civilization used a 365 day long year, called Haab, which had 19 months. Each of the first 18 months was 20 days long, and the names of the months were pop, no, zip, zotz, tzec, xul, yoxkin, mol, chen, yax, zac, ceh,
mac, kankin, muan, pax, koyab, cumhu. Instead of having names, the days of the months were denoted by numbers starting from 0 to 19. The last month of Haab was called uayet and had 5 days denoted by numbers 0, 1, 2, 3, 4. The Maya believed that this month was unlucky, the court of justice was not in session, the trade stopped, people did not even sweep the floor.
For religious purposes, the Maya used another calendar in which the year was called Tzolkin (holly year). The year was divided into thirteen periods, each 20 days long. Each day was denoted by a pair consisting of a number and the name of the day. They used 20 names: imix, ik, akbal, kan, chicchan, cimi, manik, lamat, muluk, ok, chuen, eb, ben, ix, mem, cib, caban, eznab, canac, ahau and 13 numbers; both in cycles.
Notice that each day has an unambiguous description. For example, at the beginning of the year the days were described as follows:
1 imix,
2 ik,
3 akbal,
4 kan,
5 chicchan,
6 cimi,
7 manik,
8 lamat,
9 muluk, 10 ok, 11 chuen, 12 eb, 13 ben, 1 ix, 2 mem, 3 cib, 4 caban, 5 eznab, 6 canac, 7 ahau, and again in the next period 8 imix, 9 ik, 10 akbal . . .
Years (both Haab and Tzolkin) were denoted by numbers 0, 1, : : : , where the number 0 was the beginning of the world. Thus, the first day was:
Haab: 0. pop 0
Tzolkin: 1 imix 0
Help professor M. A. Ya and write a program for him to convert the dates from the Haab calendar to the Tzolkin calendar.
Input
The date in Haab is given in the following format:
NumberOfTheDay. Month Year
The first line of the input file contains the number of the input dates in the file. The next n lines contain n dates in the Haab calendar format, each in separate line. The year is smaller then 5000.
Output
The date in Tzolkin should be in the following format:
Number NameOfTheDay Year
The first line of the output file contains the number of the output dates. In the next n lines, there are dates in the Tzolkin calendar format, in the order corresponding to the input dates.

A Plug for UNIX

Total Submissions: 9025 Accepted: 2861
Description
You are in charge of setting up the press room for the inaugural meeting of the United Nations Internet eXecutive (UNIX), which has an international mandate to make the free flow of information and ideas on the Internet as cumbersome and bureaucratic as possible.
Since the room was designed to accommodate reporters and journalists from around the world, it is equipped with electrical receptacles to suit the different shapes of plugs and voltages used by appliances in all of the countries that existed when the room was built. Unfortunately, the room was built many years ago when reporters used very few electric and electronic devices and is equipped with only one receptacle of each type. These days, like everyone else, reporters require many such devices to do their jobs: laptops, cell phones, tape recorders, pagers, coffee pots, microwave ovens, blow dryers, curling
irons, tooth brushes, etc. Naturally, many of these devices can operate on batteries, but since the meeting is likely to be long and tedious, you want to be able to plug in as many as you can. Before the meeting begins, you gather up all the devices that the reporters would like to use, and attempt to set them up. You notice that some of the devices use plugs for which there is no receptacle. You wonder if these devices are from countries that didn't exist when the room was built. For some receptacles, there are several devices that use the corresponding plug. For other receptacles, there are no devices that use the corresponding plug.
In order to try to solve the problem you visit a nearby parts supply store. The store sells adapters that allow one type of plug to be used in a different type of outlet. Moreover, adapters are allowed to be plugged into other adapters. The store does not have adapters for all possible combinations of plugs and receptacles, but there is essentially an unlimited supply of the ones they do have. Input
The input will consist of one case. The first line contains a single positive integer n (1 <= n <= 100) indicating the number of receptacles in the room. The next n lines list the receptacle types found in the room. Each receptacle type consists of a string of at most 24 alphanumeric characters. The next line contains a single positive integer m (1 <= m <= 100) indicating the number of devices you would like to plug in. Each of the next m lines lists the name of a device followed by the type of plug it uses (which is identical to the type of receptacle it requires). A device name is a string of at most 24 alphanumeric
characters. No two devices will have exactly the same name. The plug type is separated from the device name by a space. The next line contains a single positive integer k (1 <= k <= 100)
indicating the number of different varieties of adapters that are available. Each of the next k lines describes a variety of adapter, giving the type of receptacle provided by the adapter, followed by a space, followed by the type of plug.
Output
A line containing a single non-negative integer indicating the smallest number of devices that cannot be plugged in.

讨厌的青蛙 1、链接地址 https://www.doczj.com/doc/ee6605892.html,/problem?id=2812 2、问题描述 在韩国，有一种小的青蛙。每到晚上，这种青蛙会跳越稻田，从而踩踏稻子。农民在早上看到被踩踏的稻子，希望找到造成最大损害的那只青蛙经过的路径。每只青蛙总是沿着一条直线跳越稻田，而且每次跳跃的距离都相同，如图1所示。稻田里的稻子组成一个栅格，每棵稻子位于一个格点上，如图2所示。而青蛙总是从稻田的一侧跳进稻田，然后沿着某条直线穿越稻田，从另一侧跳出去，如图3所示。 问题描述
青蛙的每一跳都恰好踩在一棵水稻上，将这棵水稻拍倒。可能会有多只青蛙从稻田穿越，有些水稻被多只青蛙踩踏，如图4所示。当然，农民所见到的是图5中的情形，看不到图4中的直线。 根据图5，农民能够构造出青蛙穿越稻田时的行走路径，并且只关心那些在穿越稻田时至少踩踏了3 棵水稻的青蛙。因此，每条青蛙行走路径上至少包括3 棵被踩踏的水稻。而在一条青蛙行走路径的直线上，也可能会有些被踩踏的水稻不属于该行走路径。在图5中，格点(2, 1)、(6, 1)上的水稻可能是同一只青蛙踩踏的，但这条线上只有两棵被踩踏的水稻，因此不能作为一条青蛙行走路径；格点(2, 3)、(3, 4)、(6, 6)在同一条直线上，但它们的间距不等，因此不能作为一条青蛙行走路径；格点(2, 1)、(2, 3)、(2, 5)、(2, 7)是一条青蛙行走路径，该路径不包括格点(2, 6)。请你写一个程序，确定在所有的青蛙行路径中，踩踏水稻棵数最多的路径上有多少棵水稻被踩踏。例如，图5的答案是7，因为第6 行上全部水稻恰好构成一条青蛙行走路径。

In this paper we first studied the progress of network processing from a hardware perspective and showed that I/O and memory systems become the main bottlenecks of performance promotion. Basing on the analysis, we get the conclusion that conventional solutions for reducing I/O and memory accessing latencies are insufficient for addressing the problems. Motivated by the studies, we proposed an improved DCA combined with INIC solution which has creations in optimized architectures, innovative I/O data transferring schemes and improved cache policies. Experimental results show that our solution reduces 52.3% and 14.3% cycles on average for receiving and transmitting respectively. Also I/O and memory traffics are significantly decreased. Moreover, an investigation to the behaviors of I/O and cache systems for network processing is performed. And some conclusions about the DCA method are also presented. Keywords Keywords are your own designated keywords. 1.INTRODUCTION Recently, many researchers found that I/O system becomes the bottleneck of network performance promotion in modern computer systems [1][2][3]. Aim to support computing intensive applications, conventional I/O system has obvious disadvantages for fast network processing in which bulk data transfer is performed. The lack of locality support and high latency are the two main problems for conventional I/O system, which have been wildly discussed before [2][4]. To overcome the limitations, an effective solution called Direct Cache Access (DCA) is suggested by INTEL [1]. It delivers network packages from Network Interface Card (NIC) into cache instead of memory, to reduce the data accessing latency. Although the solution is promising, it is proved that DCA is insufficient to reduce the accessing latency and memory traffic due to many limitations [3][5]. Another effective solution to solve the problem is Integrated Network Interface Card (INIC), which is used in many academic and industrial processor designs [6][7]. INIC is introduced to reduce the heavy burden for I/O registers access in Network Drivers and interruption handling. But recent report [8] shows that the benefit of INIC is insignificant for the state of the art 10GbE network system. In this paper, we focus on the high efficient I/O system design for network processing in general-purpose-processor (GPP). Basing on the analysis of existing methods, we proposed an improved DCA combined with INIC solution to reduce the I/O related data transfer latency. The key contributions of this paper are as follows: ?Review the network processing progress from a hardware perspective and point out that I/O and related last level memory systems have became the obstacle for performance promotion. ?Propose an improved DCA combined with INIC solution for I/O subsystem design to address the inefficient problem of a conventional I/O system. ?Give a framework of the improved I/O system architecture and evaluate the proposed solution with micro-benchmarks. ?Investigate I/O and Cache behaviors in the network processing progress basing on the proposed I/O system. The paper is organized as follows. In Section 2, we present the background and motivation. In Section 3, we describe the improved DCA combined INIC solution and give a framework of the proposed I/O system implementation. In Section 4, firstly we give the experiment environment and methods, and then analyze the experiment results. In Section 5, we show some related works. Finally, in Section 6, we carefully discuss our solutions with many existing technologies, and then draw some conclusions. 2.Background and Motivation In this section, firstly we revise the progress of network processing and the main network performance improvement bottlenecks nowadays. Then from the perspective of computer architecture, a deep analysis of network system is given. Also the motivation of this paper is presented. 2.1Network processing review Figure 1 illustrates the progress of network processing.
