Function printAlarmTimings

Function printAlarmTimings: The function/method printAlarmTimings accepts three arguments – startTime, endTime and X. The startTime and endTime are two string values that represent the start time and end time of a factory. For every X minutes from the start time to the end time, the factory alarm sounds indicating the time slot for the workers.

The function/method printAlarmTimings must print the alarm timings at the factory.

Note: The start time, the end time and the alarm timings are always in 24-hr format HH:MM.

Your task is to implement the function printAlarmTimings so that it passes all the test cases.

IMPORTANT: Do not write the main() function as it is already defined.

Example Input/Output 1:
Input:
09:15
17:30
60

Output:
10:15
11:15
12:15
13:15
14:15
15:15
16:15
17:15

Explanation:
Here X=60, so the alarm sounds every 60 minutes from 09:15 to 17:30.
