接下来我们来了解一下什么是最长公共子序列(Longest Common Subsequence),我们常说的LCS就是这个最长公共子序列: 先看看维基百科是怎么定义的: 一个数列S,如果分别是两个或多个已知数列的子序列,且是所有符合此条件序列中最长的,则S 称为已知序列的最长公共子序列。 好像跟前面的最长公共子串差不多哦? 这两个还...

However, it is a non-trivial algorithm, and no one expects you to come up with this algorithm in a 45 minutes coding session. But, please go ahead and understand it, I promise it will be a lot of fun. 代码: 这里仅使用动态规划提交,马拉车算法的代码留待以后填坑。。。 class Solution: ...
