题目
编写一个函数来查找字符串数组中的最长公共前缀。
如果不存在公共前缀,返回空字符串
""
。示例 1:
输入:strs = ["flower","flow","flight"] 输出:"fl"
示例 2:
输入:strs = ["dog","racecar","car"] 输出:"" 解释:输入不存在公共前缀。
提示:
1 <= strs.length <= 200
0 <= strs[i].length <= 200
strs[i]
仅由小写英文字母组成
解析
zip
class Solution(object): def longestCommonPrefix(self, strs): """ :type strs: List[str] :rtype: str """ s = "" for i in zip(*strs): if len(set(i)) == 1: s += i[0] else: break return s
