 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.

solution:

class Solution {

public:

    bool arrayStringsAreEqual(vector<string>& word1, vector<string>& word2) {

          string result1="";

         string result2 = "";

        for(int i = 0 ; i < word1.size() ; i++)

        {

           result1  = result1 + word1[i];

        }

        for(int i = 0 ; i < word2.size() ; i++)

        {

               result2  = result2 + word2[i];

        }

        

        if(result1 == result2)

            return true;

        return false;

         

        

    }

};
