# For every set bit of a number toggle bits of other

Given two integer numbers, whenever the bits of the first number is set i.e. 1, toggle the bits of the second number leaving the rest bits of the second number unchanged.
Examples :

```Input: 2 5
Output: 7
2 is represented as 10 in binary and 5
is represented as 101. Hence toggling the
2nd bit of 5 from right, thus the new
number becomes 7 i.e. 111

Input: 1 3
Output: 2
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach:
Just do XOR of the given two Number.

## CPP

 `// A CPP program toggle bits of n2  ` `// that are at same position as set  ` `// bits of n1. ` `#include ` `using` `namespace` `std; ` ` `  `// function for the Nega_bit ` `int` `toggleBits(``int` `n1, ``int` `n2) ` `{ ` `    ``return` `n1 ^ n2; ` `} ` ` `  `// Driver program to test above ` `int` `main() ` `{ ` `    ``int` `n1 = 2, n2 = 5; ` `    ``cout << toggleBitst(n1, n2) << endl; ` `    ``return` `0; ` `} `

## Java

 `// A Java program toggle bits of n2  ` `// that are at same position as set  ` `// bits of n1. ` `import` `java.io.*; ` ` `  `class` `GFG { ` `     `  `    ``// function for the Nega_bit ` `    ``static` `int` `toggleBits(``int` `n1, ``int` `n2) ` `    ``{ ` `        ``return` `(n1 ^ n2); ` `    ``} ` `     `  `    ``// Driver program  ` `    ``public` `static` `void` `main(String args[]) ` `    ``{ ` `        ``int` `n1 = ``2``, n2 = ``5``; ` `        ``System.out.println(toggleBits(n1, n2)); ` `    ``} ` `} ` ` `  ` `  ` `  ` `  `// This code is contributed ` `// by Nikita Tiwari. `

## Python3

 `# A Python 3 program toggle bits of n2  ` `# that are at same position as set  ` `# bits of n1. ` ` `  `     `  `# function for the Nega_bit ` `def` `toggleBits(n1, n2) : ` `    ``return` `(n1 ^ n2) ` ` `  ` `  `# Driver program to test above ` `n1 ``=` `2` `n2 ``=` `5` ` `  `print``(toggleBits(n1, n2)) ` ` `  `# This code is contributed  ` `# by Nikita Tiwari. `

## C#

 `// C# program toggle bits of n2  ` `// that are at same position as set  ` `// bits of n1. ` `using` `System; ` ` `  `class` `GFG { ` `      `  `    ``// function for the Nega_bit ` `    ``static` `int` `toggleBits(``int` `n1, ``int` `n2) ` `    ``{ ` `        ``return` `(n1 ^ n2); ` `    ``} ` `      `  `    ``// Driver program  ` `    ``public` `static` `void` `Main() ` `    ``{ ` `         `  `        ``int` `n1 = 2, n2 = 5; ` `         `  `        ``Console.WriteLine(toggleBits(n1, n2)); ` `    ``} ` `} ` `  `  `// This code is contributed by Anant Agarwal. `

Output :

```7
