This article uses a two-dimensional dp array (but the space complexity is still O (M)) to redefine the meaning of the elements, which greatly reduces the code length and greatly improves the interpretability。 PS: The code of this article refers to "Algorithm 4". The name ...
KMP算法全称是Knuth-Morris-Pratt Algorithm(克努特—莫里斯—普拉特算法)实际上就是优化后的模式匹配算法。这个算法是由D.E.Knuth、J.H.Morris、V.R.Pratt这三位大佬提出。 Donald·E·Knuth大佬帅照附上 James H. Morris大佬帅照附上 Vaughan·R·Pratt大佬帅照附上 ...

Bycodechef123,history,4 years ago, KMP pattern searching is an advanced algorithm & it is hard to explain it in simple terms. I stumbled on tothis resourcerecently. I think it is a good starting point for people wanting to understand the basic idea about the KMP algorithm & its time com...
不难看出这是一道kmp板子题,直接套模板即可。对于无法匹配的情况,我们可以使用一个标记来记录,需要注意的一点是,输入的值可能会有负数,所以我们要使用int数组来存储a和b两个序列 AC代码 代码语言:javascript 复制 #include<iostream>#include<algorithm>#include<cstring>#defineIOSios::sync_with_stdio(false)using ...
We are now ready to see the code in action:Notice how short and concise this code is. I urge you to try and implement it by seeking the longest palindrome and comparing the code. That is it for this post. It was long, but I hope it will help you internalize this algorithm...
