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 ss.

Input

There are multiple test cases. The first line of input contains an integer TT (1≤T≤1061≤T≤106), indicating the number of test cases. For each test case:

The first line contains two integers aa, bb (0≤a≤23,0≤b≤590≤a≤23,0≤b≤59) and a string ss in the format of "UTC+X'', "UTC-X'', "UTC+X.Y'', or "UTC-X.Y'' (0≤X,X.Y≤14,0≤Y≤90≤X,X.Y≤14,0≤Y≤9).

Output

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

Sample Input

3

11 11 UTC+8

11 12 UTC+9

11 23 UTC+0

Sample Output

题解：就是时区时间的转换，用sscanf(s+4."%lf",&d);将小数还原到数字d;

算出0时区的时间，再转化8时区即可；

#include<bits/stdc++.h>

using namespace std;

typedef long long LL;

const LL inf=0x3f3f3f3f3f3f3f3fLL;

const int INF=0x3f3f3f3f;

int T,a,b;

char s1[10];

int main()

{

	scanf("%d",&T);

	while(T--)

	{

		scanf("%d%d",&a,&b);

		int sum=a*60+b;

		scanf("%s",s1);

		double x;

		int num= s1[3]=='+'? 1:-1;

		sscanf(s1+4,"%lf",&x);

		int cx=(int)(10*x);

		sum=sum+cx*num*6-8*60;

		int h=sum%(24*60);

		if(h<0) h+=24*60;

		printf("%02d:%02d\n",h/60,h%60);

	}

	return 0;

}
