Dado un String str y la tarea es verificar que la suma del valor ASCII de todos los caracteres sea un cuadrado perfecto o no.
Ejemplos:
C++
// 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";
}
Java
// Java program to find if string
// is a perfect square or not.
import java.io.*;
class GFG {
static boolean 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.charAt(i);
// Find floating point value
// of square root of x.
long squareRoot = (long)Math.sqrt(sum);
// If square root is an integer
return ((squareRoot -
Math.floor(squareRoot)) == 0);
}
// Driver code
public static void main (String[] args)
{
String str = "d";
if (isPerfectSquareString(str))
System.out.println("Yes");
else
System.out.println("No");
}
}
