π§© Add Binary β LeetCode Problem 67 (C++)
π Problem Description
This program adds two binary strings and returns their sum as a binary string.
The logic simulates manual binary addition β moving from the least significant bit (rightmost) to the most significant bit (leftmost), while carrying over when necessary.
This implementation focuses on string manipulation, bit logic, and carry handling, making it an excellent problem for improving algorithmic reasoning in C++.
