Grokking the Coding Interview Patterns in Go

Solution: Is Subsequence

Explore how to use the two-pointer pattern to solve the subsequence problem by matching characters from one string within another. Understand the algorithmic approach to decide if all characters appear in order without extra space, preparing you for similar coding interview challenges.

We'll cover the following...

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.
