Abhishek Mishra Problem- 3(Square root)

#include <bits/stdc++.h>
using namespace std;

float squareRoot(int n, int pre)
{
int start = 0, end = n;
int mid;
float ans;

while (start <= end) {
    mid = (start + end) / 2;
    if (mid * mid == n) {
        ans = mid;
        break;
    }
    if (mid * mid < n) {
        start = mid + 1;
        ans = mid;
    }
    else {
        end = mid - 1;
    }
}

float increment = 0.1;
for (int i = 0; i < pre; i++) {
    while (ans * ans <= n) {
        ans += increment;
    }
    ans = ans - increment;
    increment = increment / 10;
}
return ans;

}

int main()
{
int num;
cout<<"Enter the Number" << endl;
cin>>num;

int precision;
cout<<"enter upto which decimal position you want" << endl;
cin>>precision;

cout << squareRoot(num, precision) << endl;



return 0;
