题目: Given two strings, find the longest common subsequence (LCS). Your code should return the length of LCS. Clarification What's the definition of Longest Common Subsequence? https://en.wikipedia.org/wiki/Longest_common_subsequence_problem http://ba…

Given an unsorted array of integers, find the length of longest increasing subsequence. For example, Given [10, 9, 2, 5, 3, 7, 101, 18], The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Note that there may be more than…

题目: Write a function to find the longest common prefix string amongst an array of strings. 思路:求最长前缀子串,假设第一个字符串是最长前缀子串,采用增强for得到数组中每个字符串,分别与第一个字符串的同一位置进行比较,有一个字符串在该位置不一致,就返回. public class Solution { public String longestCommonPrefix(String[] strs) { i…
