Matryoshka Dolls This is the problem I am stuck on. I wrote the source code in C++, which is down below. It failed on the 2nd test. 

#include<iostream>
using namespace std;

int main(){
    int s, x;
    cin >> s >> x;
    cout << (s-x)/x << endl;
}

If you have some time to spare, please help me. Thank you!!

As mentioned, the idea is so simple. The statement of problem clearly says what you need to do. Initially you have size S, next one should be S/X according to the statement, Then the next one is (S/X)/X, So what you need to calculate is logarithm S to the base X. This can be done using while loop.
