Problem: Converting 12-hour clock times to 24-hour clock times

#### Part 1: Convert these times into 24-hour clock times

The task is to convert the given 12-hour clock times into 24-hour clock times. Here's how to do it:

- AM Times: For times in the morning (before 12:00 PM), the 24-hour time is the same as the 12-hour time.
- PM Times: For times in the afternoon or evening (after 12:00 PM), add 12 to the hour part of the time.

Let's solve each one step by step:

##### Left Column (AM Times):
1. 3:25 AM → Already in 24-hour format: 03:25
2. 7:20 AM → Already in 24-hour format: 07:20
3. 8:05 AM → Already in 24-hour format: 08:05
4. 12:20 AM → Already in 24-hour format: 00:20
5. 1:16 AM → Already in 24-hour format: 01:16
6. 4:56 AM → Already in 24-hour format: 04:56
7. 10:42 AM → Already in 24-hour format: 10:42
8. 12:51 AM → Already in 24-hour format: 00:51

##### Right Column (PM Times):
1. 3:25 PM → Add 12 to the hour: 15:25
2. 7:20 PM → Add 12 to the hour: 19:20
3. 8:05 PM → Add 12 to the hour: 20:05
4. 12:20 PM → Already in 24-hour format: 12:20
5. 1:16 PM → Add 12 to the hour: 13:16
6. 4:56 PM → Add 12 to the hour: 16:56
7. 10:42 PM → Add 12 to the hour: 22:42
8. 12:51 PM → Already in 24-hour format: 12:51

#### Final Answers for Part 1:
