Solution: Strobogrammatic Number

Understand how to use the two pointers technique to check if a given string representing a number is strobogrammatic. This lesson guides you through verifying digits from the outside in, teaching you to compare mirrored pairs based on strobogrammatic mappings, and coding this solution with optimal time and 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 ...
