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…

Write a function to find the longest common prefix string amongst an array of strings. If there is no common prefix, return an empty string "". Example 1: Input: ["flower","flow","flight"] Output: "fl" Exa…

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> &…

题目 Write a function to find the longest common prefix string amongst an array of strings. 分析 该题目是求一个字符串容器中所有字符串的最长公共前缀. AC代码 class Solution { public: string longestCommonPrefix(vector<string>& strs) { if (strs.size() == 0) return ""; e…

[牛客网]Longest Common Subsequence 发现只有d数组最格路 于是我们把前三个数组中相同的数记成一个三维坐标,同一个数坐标不会超过8个 从前往后枚举d,每次最多只会更新不超过8个点 而每个点更新就是找这个点三维偏序都小于它的最大的一个值+1来更新它 用KD树来维护,这个点与树中节点三维的某一维不相交就退出 可以加的剪枝是如果树中最大值+1小于当前搜到的答案就退出 然后把新的值在树中进行更新 跑的还是挺快的,0.5s不到 #include <bits/stdc++.h>…

题目:Longest Common Prefix 内容: Write a function to find the longest common prefix string amongst an array of strings. 编写一个函数来查找字符串数组中最长的公共前缀字符串. 理解题目: 如数组 ["a", "b"]   最长的公共前缀字符串是 "": 如数组 ["aa", "aa"]   最长的公…

题目简述: Write a function to find the longest common prefix string amongst an array of strings. 解题思路: class Solution: # @return a string def longestCommonPrefix(self, strs): if strs == []: return '' minl = 99999 for i in strs: if len(i) < minl: minl = l…

Write a function to find the longest common prefix string amongst an array of strings. 思路:找最长公共前缀 常规方法 string longestCommonPrefix(vector<string> &strs) { ) return ""; ) ]; string ans; ; ) { ; i < strs.size(); i++) { ].size() <= n…

Write a function to find the longest common prefix string amongst an array of strings. If there is no common prefix, return an empty string "". Example 1:            Input: ["flower","flow","flight"]               …

Longest Common Prefix Write a function to find the longest common prefix string amongst an array of strings. 题目的意图 It seems that it is not to check between pair of strings but on all the strings in the array. For example: {"a","a",&quo…
