# Reverse the binary representation of a number.

**Objective:** **Write a program to Reverse the binary representation of a number**

**Example: **

Input : 30 Output : 15Explanation: binary representation of 30 is : 11110 reverse of binary representation : 01111 decimal of reversed binary representation is : 15

**Input:** A Number

**Output: Decimal of reversed binary representation of a number.**

**Approach: **

- Initialize int res =0
- Now from a number , take one bit at a time
- take AND of that bit with 1 and then OR with res and store it in res
- make right shift in number by 1
- make left shift in res by 1

**Complete Code:**

**Output:**

Binary rotation of 30 is : 15
