Longest Common Prefix leetcode java 题目: Write a function to find the longest common prefix string amongst an array of strings. 题解: 解题思路是,先对整个String数组预处理一下,求一个最小长度(最长前缀肯定不能大于最小长度)。 然后以第0个字符串作为参照,从第1个字符串到最后一个字符串,对同一位置...

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。  
leetcode 14. Longest Common Prefix 给n个字符串,求最长公公前缀。直接逐位扫判断就行。 class Solution(object): def longestCommonPrefix(self, strs): """ :type strs: List[str] :rtype: str """ lenS = len(strs) if lenS == 0: return ''...
