Проверьте, является ли число, образованное конкатенацией двух чисел, полным квадратом

Опубликовано: 5 Марта, 2022

Даны два числа a и b, и задача состоит в том, чтобы проверить, является ли конкатенация a и b идеальным квадратом.
Примеры:

Input: a = 1, b = 21
Output: Yes
121 = 11 × 11, is a perfect square.
Input: a = 100, b = 100
Output: No
100100 is not a perfect square.

Рекомендуется: сначала попробуйте свой подход в {IDE}, прежде чем переходить к решению.

Approach: Initialize the number as strings initially and concatenate them. Convert the string to a number using Integer.valueOf() function. Once the string has been converted to a number, check if the number is a perfect square or not.
Below is the implementation of the above approach.

C++

// C++ program to check if the
// concatenation of two numbers
// is a perfect square or not
#include <bits/stdc++.h>
using namespace std;
 
// Function to check if
// the concatenation is
// a perfect square
void checkSquare(string s1, string s2)
{
 
    // Function to convert
    // concatenation of
    // strings to a number
    int c = stoi(s1 + s2);
 
    // square root of number
    int d = sqrt(c);
 
    // check if it is a
    // perfect square
    if (d * d == c)
    {
        cout << "Yes";
    }
    else
    {
        cout << "No";
    }
}
 
// Driver Code
int main()
{
    string s1 = "12";
    string s2 = "1";
 
    checkSquare(s1, s2);
     
    return 0;
}

Java

// Java program to check if the
// concatenation of two numbers
// is a perfect square or not
import java.lang.*;
class GFG {
 
    // Function to check if the concatenation is
    // a perfect square
    static void checkSquare(String s1, String s2)
    {
 
        // Function to convert concatenation
        // of strings to a number
        int c = Integer.valueOf(s1 + s2);
 
        // square root of number
        int d = (int)Math.sqrt(c);
 
        // check if it is a perfect square
        if (d * d == c) {
            System.out.println("Yes");
        }
        else {
            System.out.println("No");
        }
    }
 
    // Driver Code
    public static void main(String[] args)
    {
        String s1 = "12";
        String s2 = "1";
 
        checkSquare(s1, s2);
    }
}

Python 3

# Python 3 program to check if the
# concatenation of two numbers
# is a perfect square or not
import math
 
# Function to check if the concatenation
# is a perfect square
def checkSquare(s1, s2):
 
    # Function to convert concatenation of
    # strings to a number
    c = int(s1 + s2)
 
    # square root of number
    d = math.sqrt(c)
 
    # check if it is a perfect square
    if (d * d == c) :
        print("Yes")
     
    else:
        print("No")
 
# Driver Code
if __name__ == "__main__":
     
    s1 = "12"
    s2 = "1"
 
    checkSquare(s1, s2)

// C# program to check if the

using System;
public class GFG {
 
    // Function to check if the concatenation is
    // a perfect square
    static void checkSquare(String s1, String s2)
    {
 
        // Function to convert concatenation
        // of strings to a number
        int c = Convert.ToInt32(s1 + s2 );//int.ValueOf(s1 + s2);
 
        // square root of number
        int d = (int)Math.Sqrt(c);
 
        // check if it is a perfect square
        if (d * d == c) {
            Console.WriteLine("Yes");
        }
        else {
            Console.WriteLine("No");
        }
    }
