7-2 and then what time (15 minutes)

Sometimes people use four digits to represent a time , such as 1106 Express 11 Zero 6 branch . Now? , Your program calculates the end time based on the start time and the elapsed time .

Read in two numbers , The first number represents the current time with such four digits , The second number is the number of minutes , Calculate the current time after so many minutes , The result is also expressed as a four digit number . When the hours are in single digits , Zero without leading , namely 5 spot 30 Points are expressed as 530. Be careful , The second number indicates that the number of minutes may exceed 60, It could also be negative .

Input format ：
Enter... On one line 2 It's an integer , They are the starting time represented by four digits 、 And the minutes passed , Separated by spaces . Be careful ： In the starting time , When the hours are in single digits , Zero without leading , namely 5 spot 30 Points are expressed as 530; The number of minutes passed may exceed 60, It could also be negative .

Output format ：
Output the termination time represented by four digits . The title ensures that the start time and end time are within the same day .

sample input ：
1120 110
sample output ：
1310

The complete code is as follows ： 

#include<stdio.h>
int main()
{
int t,p,h,m;
scanf("%d%d",&t,&p);
h=t/100;
m=t%100;
t=h*60+m+p; // The core idea is to convert it into minutes 
h=t/60;
m=t%60;
printf("%d%02d",h,m);
}
