描述
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
Note:
- 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.
解析
根据题意，只需要将 word1 和 word2 按照顺序将元素拼接起来形成字符串进行比较即可，相等为 true ，否则为 false
解答
class Solution(object):
def arrayStringsAreEqual(self, word1, word2):
"""
:type word1: List[str]
:type word2: List[str]
:rtype: bool
"""
return "".join(word1) == "".join(word2)
