1662 - Check If Two String Arrays are Equivalent.

Easy

Given two string arrays word1 and word2, return true if the two arrays represent the same string, and false otherwise.

A string is represented by an array if the array elements concatenated in order forms the string.

Example 1:

Input: word1 = "ab", "c", word2 = "a", "bc"

Output: true

Explanation:

word1 represents string "ab" + "c" -> "abc"

word2 represents string "a" + "bc" -> "abc"

The strings are the same, so return true.

Example 2:

Input: word1 = "a", "cb", word2 = "ab", "c"

Output: false

Example 3:

Input: word1 = "abc", "d", "defg", word2 = "abcddefg"

Output: true

Constraints:

• <code>1 <= word1.length, word2.length <= 10³</code>

• <code>1 <= word1i.length, word2i.length <= 10³</code>

• <code>1 <= sum(word1i.length), sum(word2i.length) <= 10³</code>

• word1[i] and word2[i] consist of lowercase letters.
