Perfect Square String

Given a String str and the task is to check sum of ASCII value of all characters is a perfect square or not.

Examples :

Input : ddddddddddddddddddddddddd
Output : Yes

Input : GeeksForGeeks
Output : No

Algorithm



  • Calculate the string length
  • Calculate sum of ASCII value of all characters
  • Take the square root of the number sum and store it into variable squareRoot
  • Take floor value of the squareRoot and subtract from squareRoot
  • If the difference of floor value of squareRoot and squareRoot is 0 then print “Yes” otherwise “No”

Below is the implementation of the above approach :

// C++ program to find if string is a
// perfect square or not.
#include <bits/stdc++.h>
using namespace std;
  
bool isPerfectSquareString(string str)
{
    int sum = 0;
      
    // calculating the length of
    // the string
    int len = str.length();
      
    // calculating the ASCII value
    // of the string
    for (int i = 0; i < len; i++)
        sum += (int)str[i];
      
    // Find floating point value of
    // square root of x.
    long double squareRoot = sqrt(sum);
      
    // If square root is an integer
    return ((squareRoot - 
             floor(squareRoot)) == 0);
}
  
// Driver code
int main()
{
    string str = "d";
      
    if (isPerfectSquareString(str))
        cout << "Yes";
    else
        cout << "No";
}
