Solution: Is Subsequence
Explore how to use two pointers to verify if one string is a subsequence of another. This lesson guides you through the step-by-step process to advance pointers correctly, helping you implement a solution with linear time complexity and constant space usage.

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.
