#include <iostream>
#include <vector>
#include <math.h>
#include <iomanip>
#define ACCURACITY 4
using namespace std;

int main()
{
    vector<double> m;
    while (1)
    {
        double tmp;
        cin>>tmp;
        if (cin.eof()){break;}
        m.push_back(tmp);
    }
    for (int i=m.size()-1; i > -1; --i)
    {
        cout<<endl<<setprecision(ACCURACITY)<<fixed<<sqrt(m[i]);
    }
}

the results are the same with results of the task
