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
// Java program of above approach class GfG { // function to obtain the new time static void findTime(String T, int K) { // convert the given time in minutes int minutes = ((T.charAt(0) - '0') * 10 + T.charAt(1) - '0') * 60 + ((T.charAt(3) - '0') * 10 + T.charAt(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) { System.out.print("0" + hour + ":"); } else { System.out.print(hour + ":"); } // Print the minute in appropriate format if (min < 10) { System.out.println("0" + min); } else { System.out.println(min); } } // Driver code public static void main(String[] args) { String T = "21:39"; int K = 43; findTime(T, K); } } // This code is contributed by Prerna Saini |

Output:
22:22
Time Complexity: O(1)
Auxiliary Space: O(1)
