Solution: Strobogrammatic Number

Explore the two pointers technique to identify strobogrammatic numbers by comparing digit pairs from both ends of a string. Understand how to use a fixed mapping for digits that appear the same when rotated 180 degrees. This lesson helps you implement a clear and efficient approach with linear time and constant space complexity.

Statement

Given a string num representing an integer, determine whether it is a strobogrammatic number. Return TRUE if the number is strobogrammatic or FALSE if it is not.

Note: A strobogrammatic number appears the same when rotated 180180 ...
