Check If Two String Arrays are Equivalent
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
trueBoth arrays represent the string "abc", so return true.
Example 2
Input
word1 = ["a","cb"], word2 = ["ab","c"]Output
falseThe first array represents "acb" while the second represents "abc", so return false.
Constraints
- 1 <= word1.length, word2.length <= 10^3
- 1 <= word1[i].length, word2[i].length <= 10^3
- 1 <= sum(word1[i].length), sum(word2[i].length) <= 10^3
- word1[i] and word2[i] consist of lowercase letters.
