You are given a time T in 24-hour format (hh:mm) and a positive integer K, you have to tell the time after K minutes in 24-hour time.
Examples:
Input: T = 12:43, K = 21 Output: 13:04 Input: T = 20:39, K = 534 Output: 05:33
Approach:
- Convert the given time in minutes
- Add K to it let it be equal to M.
- Convert the M minutes in 24 hours format accordingly.
C++
#include <bits/stdc++.h> using namespace std;
// function to obtain the new time void findTime(string T, int K)
{ // convert the given time in minutes
int minutes = ((T[0] - '0' )
* 10
+ T[1] - '0' )
* 60
+ ((T[3] - '0' )
* 10
+ T[4] - '0' );
// Add K to current minutes
minutes += K;
// Obtain the new hour
// and new minutes from minutes
int hour = (minutes / 60) % 24;
int min = minutes % 60;
// Print the hour in appropriate format
if (hour < 10) {
cout << 0 << hour << ":" ;
}
else {
cout << hour << ":" ;
}
// Print the minute in appropriate format
if (min < 10) {
cout << 0 << min;
}
else {
cout << min;
}
} // Driver code int main()
{ string T = "21:39" ;
int K = 43;
findTime(T, K);

// Java program of above approach class GfG {

+ ((T.charAt( 3 ) - '0' )
* 10

// Add K to current minutes
minutes += K;
// Obtain the new hour
