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:

my c++ solution to codechef NUKES - "nuclear reactors" problem: http://ideone.com/7omT5g
#include <iostream>
using namespace std;

int main() {
// your code goes here
int a, n, k;
cin>>a>>n>>k;
while(k--) {
cout<<a%(n+1)<<" "; a=a/(n+1);
}
return 0;
