Explanation:
We need to convert times from 12-hour format (with am/pm) to 24-hour format.

Here’s how it works:
- For am times:
- 12:00am → 00:00
- Anything else (like 1:00am, 2:35am, etc.) stays the same hour number, just drop “am”.
- Example: 8:55am → 08:55
- For pm times:
- 12:00pm → 12:00
- Anything else (like 1:00pm, 3:35pm, etc.): add 12 to the hour.
- Example: 3:35pm → 3 + 12 = 15 → 15:35

Let’s go one by one:

1. 3:35pm → 3 + 12 = 15 → 15:35
2. 8:55am → stays same → 08:55
3. 9:15pm → 9 + 12 = 21 → 21:15
4. 6:40am → stays same → 06:40
5. 5:00pm → 5 + 12 = 17 → 17:00
6. 4:45am → stays same → 04:45
7. 7:30pm → 7 + 12 = 19 → 19:30
8. 2:35am → stays same → 02:35
9. 4:15pm → 4 + 12 = 16 → 16:15
10. 5:30am → stays same → 05:30
11. 6:45pm → 6 + 12 = 18 → 18:45
12. 10:55am → stays same → 10:55
13. 10:00pm → 10 + 12 = 22 → 22:00
14. 11:15am → stays same → 11:15
15. 3:50pm → 3 + 12 = 15 → 15:50
16. 9:20am → stays same → 09:20
17. 7:35pm → 7 + 12 = 19 → 19:35
18. 2:50am → stays same → 02:50
19. 10:25pm → 10 + 12 = 22 → 22:25
20. 11:30am → stays same → 11:30

Double-check a few:
- 12:00pm is 12:00 — not in list, good.
- 12:00am would be 00:00, but none here.
- All pm times >12? Yes, we added 12 correctly.
- All am times kept as-is (except leading zero for single-digit hours — standard 24h format uses two digits for hour).

Final Answer:
1. 15:35
2. 08:55
3. 21:15
4. 06:40
5. 17:00
6. 04:45
7. 19:30
8. 02:35
9. 16:15
10. 05:30
11. 18:45
12. 10:55
13. 22:00
14. 11:15
15. 15:50
16. 09:20
17. 19:35
18. 02:50
19. 22:25
20. 11:30
