بيان المشكلة

Time Addition (24-hour format, Next Day)

You are given a time in 24-hour format (HH MM) and a duration in minutes (k). Your task is to compute the resulting time after adding the duration to the initial time.

If the resulting time is past midnight (i.e., it falls on the next day), append Next day to the output.

Examples

  • Adding 25 minutes to 23:50 results in 00:15 Next day
  • Adding 30 minutes to 10:05 results in 10:35

Notes

  • Use proper formatting with leading zeros for hours and minutes (e.g., 05:07)
  • You may find the modulo operator (%) helpful for handling time wraparound

قيود

0 ≤ HH ≤ 23 0 ≤ MM ≤ 59 0 ≤ k ≤ 2000

تنسيق الإدخال

Input consists of:

  • A line containing two integers HH and MM, representing the starting time in 24-hour format.
  • A second line containing a single integer k, the number of minutes to add.

تنسيق الإخراج

Output the resulting time in HH:MM format.

If the result is past midnight (i.e., the next day), append Next day to the output line.

Example outputs:

  • 10:35
  • 00:15 Next day
