#include<iostream>
inline int f(int exp, int balls);
int f(int exp, int balls)
{
if(exp == 0 || balls == 0)
return 0 ;
return f(exp-1, balls)+ f(exp-1,balls-1)+1 ;
}
int main()
{
int experince{0};
int balls {0};
int floors {0};
std::cout<<"Please enter the number of floors: ";
std::cin>>floors;
std::cout <<"\nPlease enter the number of balls: ";
std::cin>>balls;
while(true)
