Here's a problem I crossed lately: You have a large String S, and q queries, each query consist of a small string b. The answer of each query is to find thelengthof the longest common substring between S and b. ( |S| <= 10^5, |b| <= 100, q <= 100 ) My dp solution to...
如果把数组换成字符串,这道题就是 Longest Common Substring 的问题。当然,这个和 最长子序列 Longest Common Subsequence 是不一样的。 类似求极值的题,都要用DP想一想。本题就可以用DP来做。 dp[i][j] 表示a数组0~i 和 b数组前0~j,所能得到的最大相同子数组(末尾能匹配的最大长度)。 如果当前正在遍...

这道题给了我们两个数组A和B,让我们返回连个数组的最长重复子数组。那么如果我们将数组换成字符串,实际这道题就是求Longest Common Substring的问题了,而貌似LeetCode上并没有这种明显的要求最长相同子串的题,注意需要跟最长子序列Longest Common Subsequence区分开,关于最长子序列会在follow up中讨论。好,先来看这...

There is a randomized algorithm that solves the Longest Common Substring with don't cares problem on two strings of length n in k1.5n2/2ω(√log n) time. Given two strings S, T of length n, there is a randomized algorithm ... A Abboud,RR Williams,H Yu - Society for Industrial and...
The similarity between a pair of time series, i.e., sequences of indexed values in time order, is often estimated by the dynamic time warping (DTW) distance, instead of any in the well-studied family of measures including the longest common subsequence (LCS) length and the edit distance....
