1、 ACM：Association for Computing Machinery 美国计算机协会 ICPC：International Collegiate Programming Contest 国际大学生程序设计竞赛 ACM/ ICPC 由美国计算机协会主办的国际大学生程序设计竞赛ACM/ICPC 是世界上公认的历史悠久、规模最大、水平最高的国际大学生程序设计竞赛。 5 6 如何比赛？ 3人 组 队 7 9 如 何 排 名 ？ 10 11 12 C:scanf 速 度 快 printf 格 式 容 易 控 制 C+: cin 使 用 简 单 , 自 动 识 别 类 型 cout 格 式 控

2、 制 较 麻 烦数 据 规 模 较 大 时 , 推 荐 (必 须 )使 用scanf 以 避 免 超 时 (TLE)C和 C+的 输 入 输 出 混 合 使 用 29 30Problem DescriptionYour task is to Calculate a + b.Too easy?! Of course! I specially designed the problem for ACM beginners. You must have found that some problems have the same titles with this one, yes, all these

3、 problems were designed for the same aim. InputThe input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line. OutputFor each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each li

4、ne in input. Sample Input1 510 20Sample Output630 31 32 33 34Problem DescriptionYour task is to Calculate a + b.InputInput contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line. OutputFo

5、r each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input. Sample Input21 510 20Sample Output630 35 for( i=0 ; in ; i+ ) 36 Problem DescriptionYour task is to Calculate a + b.InputInput contains multiple test cases. Eac

6、h test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.OutputFor each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for ea

7、ch line in input. Sample Input1 510 200 0Sample Output630 Problem DescriptionYour task is to Calculate the sum of some integers.InputInput contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input

8、and this test case is not to be processed.OutputFor each group of input integers you should output their sum in one line, and with one line of output for each line in input. Sample Input4 1 2 3 45 1 2 3 4 50 Sample Output1015 Problem DescriptionYour task is to calculate the sum of some integers.Inpu

9、tInput contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line. OutputFor each group of input integers you should output their sum in one line, and with one line of output for each line in input. Sample Input24

10、1 2 3 45 1 2 3 4 5Sample Output1015 Problem DescriptionYour task is to calculate the sum of some integers.InputInput contains multiple test cases, and one case one line. Each case starts with an integer N, and then N integers follow in the same line. OutputFor each test case you should output the su

11、m of N integers in one line, and with one line of output for each line in input. Sample Input4 1 2 3 45 1 2 3 4 5Sample Output1015 Problem DescriptionYour task is to Calculate a + b.InputThe input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per l

12、ine. OutputFor each pair of input integers a and b you should output the sum of a and b, and followed by a blank line. Sample Input1 510 20Sample Output630 Problem DescriptionYour task is to calculate the sum of some integers.InputInput contains an integer N in the first line, and then N lines follo

13、w. Each line starts with a integer M, and then M integers follow in the same line. OutputFor each group of input integers you should output their sum in one line, and you must note that there is a blank line between outputs.Sample Input34 1 2 3 45 1 2 3 4 53 1 2 3Sample Output10 156 43 最 好 不 要 进 行 函

14、 数 声 明 变 量 定 义 在 使 用 之 前 避 免for(int i = 0;i n ;i+) i的 使 用 范 围 仅 仅 在 for内 部 ， 容 易 导 致 CE 遇 到 问 题 首 先 自 己 查 找 资 料 ， 之 后 再 提 问 44Problem DescriptionGive you an operator (+,-,*, / -denoting addition, subtraction, multiplication, division respectively) and two positive integers, your task is to output th

15、e result. Is it very easy? Come on, guy! PLMM will send you a beautiful Balloon right now!Good Luck!InputInput contains multiple test cases. The first line of the input is a single integer T (0 T1 0 0 0 ) which is the number of test cases. T test cases follow. Each test case contains a char C (+,-,*

16、, /) and two integers A and B(0 A,B1 0 0 0 0 ).Of course, we all know that A and B are operands and C is an operator. OutputFor each case, print the operation result. The result should be rounded to 2 decimal places If and only if it is not an integer.Sample Input4+ 1 2- 1 2* 1 2/ 1 2Sample Output3-120.50 45有什么问题？
