题目链接 https://www.patest.cn/contests/pat-a-practise/1065 思路 因为 a 和 b 都是 在 long long 范围内的 但是 a + b 可能会溢出 long long 但是 不会溢出 long double 所以 用long double 就能轻松解决了 或者 用大数加法 也行 AC代码 #include <cstdio> #include <cstring> #include <ctype.h> #includ…

题目 Given three integers A, B and C in [-263, 263], you are supposed to tell whether A+B > C. Input Specification: The first line of the input gives the positive number of test cases, T (<=10).  Then T test cases follow, each consists of a single lin…

第一眼以为是大数据,想套个大数据模板,后来发现不需要.因为A.B.C的大小为[-2^63, 2^63],用long long 存储他们的值和sum. 接下来就是分类讨论:如果A > 0, B < 0 或者 A < 0, B > 0,sum不会溢出,直接和C判断比较即可.如果A > 0, B > 0,sum可能会溢出, 溢出的话为负数,所以sum < 0时候说明溢出了,那么肯定是大于C的.如果A < 0, B < 0,sum可能会溢出,同理,sum &g…
