Is Subsequence?
Given a string s and a string t , check if s is subsequence of t . A subsequence of a string is a new string which is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters. (ie, "ace" is a subsequence of "abcde" while "aec" is not). Follow up: If there are lots of incoming S, say S1, S2, ... , Sk where k >= 1B, and you want to check one by one to see if T has its subsequence. In this scenario, how would you change your code? Example 1: Input: s = "abc", t = "ahbgdc" Output: true Example 2: Input: s = "axc", t = "ahbgdc" Output: false Constraints: 0 <= s.length <= 100 0 <= t.length <= 10^4 Both strings consists only of lowercase characters. class Solution { public boolean isSubsequence(String s, String t) { if(s.length()==0) ...
