13. Is Subsequence
Easy
Description
Given two strings s and t, return true if s is a subsequence of t, or false otherwise.
A subsequence of a string is a new string that is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters. (i.e., "ace" is a subsequence of "abcde" while "aec" is not).
Examples
Input:
s = "abc", t = "aebdc"
Output:
true
Input:
s = "axc", t = "ahbgdc"
Output:
false
Constraints
- • 0 <= s.length <= 100
- • 0 <= t.length <= 10^4
- • s and t consist only of lowercase English letters.
