Is Subsequence Problem: Two Pointer Technique Vs Preprocessing
Two-pointer technique solves LeetCode 392: Is Subsequence in O(n+m) time, traversing strings s and t to check if s is a subsequence of t.
Top Interview 150 The Is Subsequence problem is a great challenge that involves iterating through strings to determine if one is a subsequence of the other. Let’s break down LeetCode 392: Is Subsequence and explore both standard and optimized solutions. 🚀 Problem Description Given two strings s and t: Return true if s is a subsequence of t. A subsequence of a string is formed by deleting some characters (or none) from the original string without changing the relative order of the remaining characters. 💡 Examples Example 1 Input: s = "abc", t = "ahbgdc" Output: true...
