http://codeforces.com/contest/816/problem/A 题意: 给出一个时间,问最少过多少时间后是回文串. 思路: 模拟,先把小时的逆串计算出来: ① 如果逆串=分钟,那么此时已经是回文串了. ② 如果逆串>分钟,那么只需要逆串-分钟即可.(注意此时逆串>=60的情况) ③ 如果逆串<分钟,此时在这个小时内要构成回文串已经是不可能的了,那么就加上60-minute分钟,进入一个新的小时,然后重复上述步骤. #include<iostream>…
1.题目A:Karen and Morning 题意: 给出hh:mm格式的时间,问至少经过多少分钟后,该时刻为回文字符串? 思路: 简单模拟,从当前时刻开始,如果hh的回文rh等于mm则停止累计.否则,根据rh和mm的大小来累计sum,然后hh+1,不断尝试. #include<iostream> using namespace std; int main() { int hh,mm; char c; while (cin >> hh >> c >> mm…
