Solution: Is Subsequence
Understand how to apply the two pointers approach to check if one string is a subsequence of another. This lesson guides you through initializing pointers, iterating through both strings, and verifying the subsequence condition with an optimal algorithm that runs in linear time and uses constant space.

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.
