Problem Description

Chiaki often participates in international competitive programming contests. The time zone becomes a big problem.
Given a time in Beijing time (UTC +8), Chiaki would like to know the time in another time zone s.

 

Input

There are multiple test cases. The first line of input contains an integer T (1≤T≤106), indicating the number of test cases. For each test case:
The first line contains two integers a, b (0≤a≤23,0≤b≤59) and a string s in the format of "UTC+X'', "UTC-X'', "UTC+X.Y'', or "UTC-X.Y'' (0≤X,X.Y≤14,0≤Y≤9).

 

Output

For each test, output the time in the format of hh:mm (24-hour clock).

 

Sample Input

3 11 11 UTC+8 11 12 UTC+9 11 23 UTC+0

 

Sample Output

11:11 12:12 03:23

 题意：

这就是说给你一个时间HH：MM表示，然后让你一北京卫时间时区，给你一个新时区，让你计算新时区的时间，就是一道模拟题，注意一下正负14时区，正负0时区，还有就是，虽然是28时区，但是用的是24小时制，也就是在24时是0时。

算法：

纯模拟，就是注意一些细节情况就行了。也不是太难的模拟题。

代码：

#include<iostream>
#include<cstdio>
#include<string.h>
using namespace std;

int main()
{
    int T;
    scanf("%d",&T);
    while(T--)
    {
        int h,m;
        int x = 0,y = 0;
        char s[10] = {0};
        memset(s,'0',sizeof(s));
        scanf("%d%d%s",&h,&m,s);
        if(s[4] == '1')
        {
            x += s[4]-'0';
            if('0' <= s[5] && s[5] <= '9')
            {
                x *= 10;
                x += s[5]-'0';
                y = s[7]-'0';
            }
            else

这是我AC了的代码，开始被卡住了，14时区每分好...............选择咬舌自尽.。。。。。
