MOP Coin Combo Finder
1.
Save your file as "ClassNumber_YourName_Ex01.py"
Use Macanese coins of 1 MOP, 5 MOP, and 10 MOP to find all combinations that total exactly 63 MOP.
2
Use only coins of 1 MOP, 5 MOP, and 10 MOP denominations.
1
Each combination must total exactly 63 MOP.
4
Use exactly three nested while loops to generate the combinations.
5
Print each valid result in the format: 1*c1 + 5*c5 + 10*c10 = 63.
6
Output Example
3
No coin count may exceed 63.
1*63 + 5*0 + 10*0 = 63
1*58 + 5*1 + 10*0 = 63
1*53 + 5*2 + 10*0 = 63
1*48 + 5*3 + 10*0 = 63
1*43 + 5*4 + 10*0 = 63
1*38 + 5*5 + 10*0 = 63
1*33 + 5*6 + 10*0 = 63
1*28 + 5*7 + 10*0 = 63
1*23 + 5*8 + 10*0 = 63
1*18 + 5*9 + 10*0 = 63

Two-Hour Clock Coincidence
1.
Save your file as "ClassNumber_YourName_Ex02.py"
Brute-force all second granularity times 00:00:00 – 02:00:00 with loops h, m, s. Print those times.
2
Loop through all times from
00:00:00 up to and including
02:00:00,
printing each second.
1
Use three nested loops over hour h (0–2), minute m (0–59), and second s (0–59), but stop exactly at 02:00:00.
4
Output Example
3
Print the time (in
HH:MM:SS format)
