Write a function to find the longest common prefix string amongst an array of strings. 这道题让我们求一系列字符串的共同前缀,没有什么特别的技巧,无脑查找即可,我们定义两个变量i和j,其中i是遍历搜索字符串中的字符,j是遍历字符串集中的每个字符串.这里将单词上下排好,则相当于一个各行长度有可能不相等的二维数组,我们遍历顺序和一般的横向逐行遍历不同,而是采用纵向逐列遍历,在遍历的过程中,如果某一行没有了,说明其为…

问题: Write a function to find the longest common prefix string amongst an array of strings. 官方难度: Easy 翻译: 寻找一个字符串数组的最长公共前缀. 方法一: 数组长度为0,返回空字符串. 将数组第一项,作为初始的公共前缀. 从数组第二项开始进入循换,整理当前字符和当前前缀字符的长度. 以小长度的字符串为基准,从头开始逐个匹配,遇到不同的字符时,更新前缀字符. 为防止完全匹配情况,如"aa"…
