1662. Check If Two String Arrays are Equivalent - Leetcode
In this YouTube video, we will delve into LeetCode problem number 1662, titled "Check If Two String Arrays are Equivalent." This problem is categorized as easy, and we will provide a comprehensive step-by-step explanation.
The problem can be summarized as follows:
*Problem Statement:*
You are given two string arrays, `word1` and `word2`. Your task is to determine whether these two arrays represent the same string. In simpler terms, you need to check if the elements of these arrays, when concatenated in order, form the same string.
*Example 1:*
Input: `word1 = ["ab", "c"], word2 = ["a", "bc"]`
Output: `true`
Explanation:
`word1` represents the string "ab" + "c" = "abc".
`word2` represents the string "a" + "bc" = "abc".
As both `word1` and `word2` represent the same string "abc," the function should return `true`.
*Example 2:*
Input: `word1 = ["a", "cb"], word2 = ["ab", "c"]`
Output: `false`
Explanation:
`word1` represents the string "a" + "cb" = "acb".
`word2` represents the string "ab" + "c" = "abc".
Since `word1` and `word2` represent different strings ("acb" and "abc" respectively), the function should return `false`.
*Example 3:*
Input: `word1 = ["abc", "d", "defg"], word2 = ["abcddefg"]`
Output: `true`
Explanation:
`word1` represents the string "abc" + "d" + "defg" = "abcddefg".
`word2` represents the string "abcddefg".
As both `word1` and `word2` represent the same string "abcddefg," the function should return `true`.
