ACM知识点

1.结果输出行最后不能有空格，真操蛋啊
2.ALT +F8快速整理代码格式
3.%x   可以先%x，得到运算结果再%x，否则容易运算超时
4.Ctrl+F5运行程序，不用再system("pause")了
5.The input consists of multiple test cases. Each test case contains 3 integers A, B and n on a single line (1 <= A, B <= 1000, 1 <= n <= 100,000,000). Three zeros signal the end of input and this test case is not to be processed.输入数字的范围不用理它？
