Count square numbers in a range(n,m)

Input  : n = 5, m = 100
Output : 8
The numbers with odd factors are 9, 16, 25, 
36, 49, 64, 81 and 100

Input  : n = 8, m = 65
Output : 6

Input  : n = 10, m = 23500
Output : 150

source code:-

#include <bits/stdc++.h>

using namespace std;

 

int Squares(int n, int m)

{

   return (int)pow(m,0.5) - (int)pow(n-1,0.5);

}

 

// Driver code

int main()

{

    int n = 5, m = 100;

    cout << "Count is " << Squares(n, m);

    return 0;

}
