Given an array A of strings, find any smallest string that contains each string inAas a substring. We may assume that no string inAis substring of another string inA. Example 1: Input:["alex","loves","leetcode"]Output:"alexlovesleetcode"Explanation:All permutationsof"alex","loves","leet...
Can you solve this real interview question? Find the Shortest Superstring - Given an array of strings words, return the smallest string that contains each string in words as a substring. If there are multiple valid strings of the smallest length, return
由于最后要返回字符串,还需要 bp 来记录 argmin 的值(也就是使得 C(S,j)最小的i的值),这样最后就可以从 min dp[(1<<n)-1][j] 一步步反推。 classSolution {public:stringshortestSuperstring(vector<string>&A) {intn=A.size(); vector<vector<int>> g(n,vector<int>(n));for(inti=0;i<n;...

这是一个Java语言的LeetCode题解,题目是寻找最短的超字符串。 解析:这个问题可以通过动态规划来解决。我们可以创建一个二维数组dp,其中dp[i][j]表示以第i个字符为结尾的最长超字符串的长度。然后我们遍历字符串,对于每个字符,我们都尝试将其添加到当前位置的超字符串中,如果添加后的长度大于dp[i-1][j-1],...

方法: 首先需要一个函数合并两个字符串的重叠部分,一个函数计算重叠部分的长度。主要通过dp的思想,不断合并list中字符串,每一轮都计算出重叠长度最大的两个字符串进行合并,最后list中最后的字符串即为结果。 具体实现: classFindTheShortestSuperstring{funshortestSuperstring(A:Array<String>):String{vallist=A.to...
