//1662. 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: 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:
//
//1 <= word1.length, word2.length <= 103
//1 <= word1[i].length, word2[i].length <= 103
//1 <= sum(word1[i].length), sum(word2[i].length) <= 103
//word1[i] and word2[i] consist of lowercase letters.
