what s test 3 ?

#include <iostream>
#include <cmath>
#include <iomanip>

using namespace std;

int main(){

    long double x;
    int i=0;
    long double tab[32768];

    cout << setprecision(4) << fixed;
    cin >> x;
    while(!cin.eof()){
              tab[i]=sqrt(x);
              i+=1;
              cin >> x;
              }
    for(int k=0;k<i;k++){
                   cout << tab[i-1-k] << endl;
                   }
                   getchar();getchar();
    }

Don't use "cout" or "cin",because they're not fast.

may be array tab is too small

WA is not about speed mate, besides my guess is they r fast enough here: )
thx anyway, will remember it

WA is not about array size either. is would be memory crash than or smh like that
thx again

any other suggestions ?
