🧩 Add Binary (Python)

Description:
This program adds two binary numbers given as strings and returns their sum as a new binary string.

For example:
If a = "1010" and b = "1011",
then the output will be "10101".

The logic is simple:

  1. Start adding from the rightmost digits of both binary strings.
  2. Keep track of the carry (like normal addition).
  3. Continue adding until all digits and carry are processed.
  4. Finally, reverse the result to get the correct binary sum.

This is an easy and beginner-friendly solution to
LeetCode Problem 67 — "Add Binary".
