Reverse the binary representation of a number.
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
Code:
Binary rotation of 30 is : 15
