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

Example:

Input : 30
Output : 15
Explanation :
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
Reverse Binray representation of a Decimal

Complete Code: Run This Code

Output:

Binary rotation of 30 is : 15
