leetcode:1662. 检查两个字符串数组是否相等(python3解法)

难度:简单

        给你两个字符串数组 word1 和 word2 。如果两个数组表示的字符串相同,返回 true ;否则,返回 false 。

        数组表示的字符串 是由数组中的所有元素 按顺序 连接形成的字符串。

示例 1:

输入:word1 = ["ab", "c"], word2 = ["a", "bc"]
输出:true
解释:
word1 表示的字符串为 "ab" + "c" -> "abc"
word2 表示的字符串为 "a" + "bc" -> "abc"
两个字符串相同,返回 true

示例 2:

输入:word1 = ["a", "cb"], word2 = ["ab", "c"]
输出:false

示例 3:

输入:word1  = ["abc", "d", "defg"], word2 = ["abcddefg"]
输出:true

提示:

  • 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] 和 word2[i] 由小写字母组成

题解:

class Solution:
    def arrayStringsAreEqual(self, word1: List[str], word2: List[str]) -> bool:
        str_word1 = ''.join(word1)
        str_word2 = ''.join(word2)
        if str_word1 == str_word2:
            return True
        return False
