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

**Approach:**

Just do XOR of the given two Number.

## Javascript

`<script>` `// JavaScript program toggle bits of n2` `// that are at same position as set` `// bits of n1` `// Function for the Nega_bit` `function` `toggleBits(n1, n2)` `{` ` ` `return` `(n1 ^ n2);` `} ` `// Driver code` `let n1 = 2, n2 = 5;` `document.write(toggleBits(n1, n2));` `// This code is contributed by sanjoy_62` `</script>` |
