# 1662. Check If Two String Arrays are Equivalent

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 boolean arrayStringsAreEqual(String[] word1, String[] word2) {
String w1="";
String w2="";
for(int i=0; i<word1.length; i++)
{
w1+=word1[i];
}
String ans1=w1;
for(int i=0; i<word2.length; i++)
{
w2+=word2[i];
}
String ans2=w2;
if(w1.equals(w2))
{
return true;
}
else
return false;
}
}
