题意:

给出UTC+8的小时a和分钟b,求 "UTC+X'', "UTC-X'', "UTC+X.Y'', or "UTC-X.Y''的日期。

思路:

转成分钟计算

#include <bits/stdc++.h>
using namespace std;
typedef long long LL;
int main()
{
    int t, h, m;
    char s[20];
    cin>>t;
    while(t--)
    {
        scanf("%d%d%s", &h, &m, s);
        h = h*60+m;
        int sg = s[3]=='+'?1:-1;//符号
        double x;
        sscanf(s+4, "%lf", &x);
        x = (int)(x*10); //读浮点数会有误差
        int cha = x*6*sg-8*60;//差值
        h = (h+cha+24*60;)%(24*60);
        printf("%02d:%02d\n", h/60, h%60);
    }
    return 0;
}
