Calculate Delayed Arrival Time
We can find the delayed arrival time by adding the arrival time and the delayed time together. Since the time is in 24hour format, if the result exceeds or equals 24, we need to subtract 24 from it to get the equivalent time on the next day.
Here’s a stepbystep explanation:
 Add Arrival and Delayed Time: Sum the
arrivalTime
anddelayedTime
.  Adjust for 24hour Format: If the sum is 24 or more, subtract 24 to convert to 24hour format.
Python solution:


Explanation:
 If the arrival time is 15 and the delay is 5, then 15 + 5 = 20, so the train arrives at 20:00.
 If the arrival time is 13 and the delay is 11, then 13 + 11 = 24, but in 24hour format, we represent this as 00:00, so the function returns 0.
The code handles both cases and returns the correct arrival time in 24hour format. Its time complexity is O(1).
