  1662. Check If Two String Arrays are Equivalent
  Difficulty: 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:
  
  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.
