AC代码:
#include "stdio.h" int main() { long long a ,b ; while ( EOF != scanf( "%lld%lld" , &a , &b ) ) { printf( "%lld\n" , a > b ? a - b : b - a ) ; } return 0 ; }
本人刚刚开始进行竞赛训练,只能做些简单的题来找找感觉,以后会慢慢的规范起来。。。
做题反省:
最初没有考虑到int数据范围,之后才用double才A了。
然后,突然觉得数据范围是一个很关键的东西要好好看看才行,不!不是好好看看,而已要牢牢记住!!!
测试 double 如下:
11975345 | 10055 | Hashmat the Brave Warrior | Accepted | ANSI C | 0.149 |
11975390 | 10055 | Hashmat the Brave Warrior | Accepted | ANSI C | 0.066 | 测试 long long 如下:
