Minimum Operations to Make Binary Palindromic

Problem Overview

• Given an integer N, find the minimum number of +1/-1 operations to make its binary representation a palindrome.
• Input: N with 0 <= N <= 2*10^9; Output: the minimum operations needed.
• Domain: binary strings and number manipulation; assess when N’s base-2 form becomes palindromic.
