Solution:
#include <iostream> using namespace std; int main() { int x1, x2 , x3 , x4 ,x5, tot; cin >> x1>> x2 >> x3 >> x4 >>x5; // we got the inputs in // lets acually grab the sum tot = x1 + x2 + x3 + x4 + x5; if (tot == 0) cout << -1; // they didnt hv anything to start with else if (tot % 5 == 0 ) cout << tot /5 ; // its divisible by 5 we r good and the uniform solution is the correct else cout << -1; // else its not divisible by 5 and they didnt hv the same number of coins to start with return 0; }
