suppose input:
25 4 4
that means A=25(bombarded particles), N=4(capacity of chamber), K=4(number of chambers)
step-by-step illustration of chambers with consisting particles in it:
1: 1 0 0 0
2: 2 0 0 0
3: 3 0 0 0
4: 4 0 0 0
5: 0 1 0 0
6: 1 1 0 0
7: 2 1 0 0
8: 3 1 0 0
9: 4 1 0 0
10: 0 2 0 0
11: 1 2 0 0
12: 2 2 0 0
13: 3 2 0 0

15: 0 3 0 0
16: 1 3 0 0
17: 2 3 0 0

22: 2 4 0 0
23: 3 4 0 0
24: 4 4 0 0
25: 0 0 1 0

first of all, K = 4 here :wink: so both answers you wrote are incorrect

so what is correct answar and why?

@jhabar see the answer :wink:

yes, this one is correct :wink:
