LeetCode: Longest Common Prefix 解题报告 Longest Common Prefix Write a function to find the longest common prefix string amongst an array of strings. Show Tags SOLUTION 1: 解法很直观。先找到最小长度,然后逐个字母遍历,同时逐个遍历所有的字符串。注意各种小细节: 1. break的时候,应该返回上一个索引指...
classSolution {publicString longestCommonPrefix(String[] strs) {if(strs.length == 0)return"";intminlen =Integer.MAX_VALUE;for(String str : strs) minlen=Math.min(minlen, str.length());intlow = 1;//这里指第一个字符串inthigh =minlen;while(low <=high){intmid = (low+high)/2;if(is...
import pandas as pd class Solution(object): def longestCommonPrefix(self, strs): for i in strs: if len(i) > 200 or len(i) < 1: # 控制列表strs长度 return False if not i.islower(): # 限制strs每一个元素必须为小写 return False strs_dict = {} #为strs的每一个元素创建一个空字...
class Solution { public String longestCommonPrefix(String[] strs) { //判断边界条件 if(strs==null||strs.length==0)return ""; String res=strs[0];//取第一个 for(int i=1;i<strs.length;i++){ while(strs[i].indexOf(res)!=0){ res=res.substring(0,res.length()-1); } } retu...
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 ""。 输入: ["flower","flow","flight"] 输出: "fl" 输入: ["dog","racecar","car"] 输出: "" 相关代码 classSolution(object):deflongestCommonPrefix(self,strs):iflen(strs)==0:return''elif""instrs:return'...
public class Solution { public String longestCommonPrefix(String[] strs) { if(strs==null || strs.length==0) return ""; String result=strs[0]; for (String x:strs) { int lenMin=result.length()>x.length()?x.length():result.length(); while (lenMin>=0) { result=result.substring...
C# Sharp Basic: Exercise-94 with SolutionWrite a C# program that finds the longest common prefix from an array of strings. Sample Data: ({ "Padas", "Packed", "Pace", "Pacha" }) -> "Pa" ({ "Jacket", "Joint", "Junky", "Jet" }) -> "J" ({ "Bort", "Whang", "Yarder", ...
class Solution { public: string longestCommonPrefix(vector<string>& strs) { } }; 翻译 最长公共前缀 难度系数:简单 写一个能够在字符串数组中找到最长公共前缀的函数。 思路 将字符串数组从第一个往后匹配就好, 并用substr函数 代码 class Solution { ...
LeetCode上的原题,请参见我之前的博客Longest Common Prefix。 解法一: classSolution {public:/** * @param strs: A list of strings * @return: The longest common prefix*/stringlongestCommonPrefix(vector<string> &strs) {if(strs.empty())return"";stringres ="";for(intj =0; j < strs[0...
Write a function to find the longest common prefix string amongst an array of strings. 题目大意:求一组字符串的最长前缀。 代码如下: class Solution { public: string longestCommonPrefix(vector& strs) { if(strs.size() == 0) return ""; int minStrLen = strs[0].size(); string result; ...
