Problem: Is Subsequence

easy
15 min
Explore how to determine whether one string is a subsequence of another using the two pointers approach. This lesson helps you apply linear data structure techniques to solve this common coding interview problem efficiently, enhancing your algorithmic problem-solving skills.

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.

Constraints:

  • 00 \leq s.length 100\leq 100

  • 00 \leq t.length 104\leq 10^4

  • s and t consist only of lowercase English letters.
