Solution: Is Subsequence
Explore how to determine if one string is a subsequence of another by applying the two pointers technique. Understand the step-by-step approach that involves scanning both strings efficiently, achieving linear time complexity and constant space usage. This lesson helps you implement and reason about subsequence problems commonly encountered in coding interviews.

Statement
Given two strings s and t, determine whether s is a subsequence of t. Return TRUE if it is, or FALSE otherwise.
A subsequence of a string is a new string formed by deleting zero or more characters from the original string, without changing the relative order of the remaining characters. For example, "ace" is a subsequence of "abcde", whereas "aec" is not.
