Compare two integers without using any Comparison operator
• Difficulty Level : Basic
• Last Updated : 04 Mar, 2021

Given two integers A & B. Task is to check if A and B are same or not without using comparison operators.
Examples:

```Input : A = 5 , B = 6
Output : 0

Input : A = 5 , B = 5
Output : 1

Note : 1 = "YES" and 0 = "NO"```

idea is pretty simple we do Xor of both element ( A , B ) . if Xor is zero then two number are equal else not .
Below is the implementation of above idea :

## C++

 `// C++ program to compare two integers witout``// any comparison operator.``#include``using` `namespace` `std;` `// function return true if A ^ B > 0  else false``bool` `EqualNumber(``int` `A, ``int` `B)``{``   ``return` `( A ^ B ) ;``}` `// Driver program``int` `main()``{``  ``int` `A = 5 , B = 6;``  ``cout << !EqualNumber(A, B) << endl;``  ``return` `0;``}`

## Java

 `// Java program to compare two integers witout``// any comparison operator.``import` `java.util.*;` `class` `solution``{` `// function return true if A ^ B > 0 else false``static` `boolean` `EqualNumber(``int` `A, ``int` `B)``{``    ` `  ``if` `((A^B) != ``0``)``   ``return` `true``;``  ``else``   ``return` `false``;``}` `// Driver program``public` `static` `void` `main(String args[])``{``int` `A = ``5` `, B = ``6``;``if``(EqualNumber(A, B) == ``false``)`` ``System.out.println(``1``);``else`` ``System.out.println(``0``);` `}``}``// This code is contributed by``// Surendra_Gangwar`

## Python3

 `# Python3 program to compare two integers``# without any comparison operator.` `# Function return true if``# A ^ B > 0 else false``def` `EqualNumber(A, B):` `    ``return` `( A ^ B )` `# Driver Code``A ``=` `5``; B ``=` `6``print``(``int``(``not``(EqualNumber(A, B))))` `# This code is contributed by Smitha Dinesh Semwal.`

## C#

 `// C# program to compare two integers``// without any comparison operator.``using` `System;` `class` `GFG``{``// function return true if``// A ^ B > 0 else false``static` `bool` `EqualNumber(``int` `A, ``int` `B)``{``    ``if``(( A ^ B ) > 0)``        ``return` `true``;``    ``else``        ``return` `false``;``}` `// Driver Code``public` `static` `void` `Main()``{``    ``int` `A = 5 , B = 6;``    ``if``(!EqualNumber(A, B) == ``false``)``        ``Console.WriteLine(``"0"``);``    ``else``        ``Console.WriteLine(``"1"``);``}``}` `// This code is contributed``// by Akanksha Rai`

## PHP

 ` 0 else false``function` `EqualNumber(``\$A``, ``\$B``)``{``return` `( ``\$A` `^ ``\$B` `) ;``}` `// Driver Code``\$A` `= 5 ;``\$B` `= 6;``echo` `((int)!(EqualNumber(``\$A``, ``\$B``))) . ``"\n"``;` `// This code is contributed``// by ChitraNayal``?>`

## Javascript

 ``

Output:

`0`
