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
