Problems:Write a function to find the longest common prefix string amongst an array of strings. 就是返回一个字符串数组的所有的公共前缀.不难.我是已第一个字符串为参考,然后依次遍历其他的字符串,一旦遇到不同的.就break.然后返回第一个字符串的相应子序列. class Solution { public: string longestCommonPrefix(vector<string> &…

Longest Common Prefix 题目 给予一个列表,元素为字符串,写一个程序找出最长公共前缀 解题思路 先比较两个字符串,如果第一个字符不一样,则返回空值,比较完成后,用这个公共字符串和下一个元素继续比较,以此类推 class Solution: # @param {string[]} strs # @return {string} def longestCommonPrefix(self, strs): if not strs: return '' if len(strs) ==…

题目链接:https://leetcode.com/problems/longest-common-prefix/ 题目:Write a function to find the longest common prefix string amongst an array of strings. 解题思路:寻找字符串数组的最长公共前缀,将数组的第一个元素作为默认公共前缀.依次与后面的元素进行比較.取其公共部分,比較结束后.剩下的就是该字符串数组的最长公共前缀.演示样例代码例如以下: public…

14. Longest Common Prefix Write a function to find the longest common prefix string amongst an array of strings. 注:这题竟然连个示例都没有,说明特殊情况并不多,就是要找出所有字符串的最长公共前缀.他应该不会超过所有字符串中最短的那个,可以试着找出最短长度n,然后每个都读取和比较n个,并根据情况不断减小那个n.\ ) { return ""; } int n{int(strs…

这个也是简单题目.可是关键在于题意的理解. 题目原文就一句话:Write a function to find the longest common prefix string amongst an array of strings. 题意是给一个字符串数组,找出这个字符串数组中全部字符串的最长公共前缀. 注意是限定的前缀.而不是子串. 所以,直接的解法就是以第一个字符串为基准,逐个比較每一个字符.算法复杂度也显然是O(M*N).M是字符串的个数,N是最长前缀的长度. 代码例如以下: class…
