Kmp has been doing this for the past few days. Today, we have A question about hdu 1711, which is A simple kmp template question; The core of kmp is the next array, which has been reading Yan Weimin's Data Structure textbooks over the past few days.

Description For the daily milking, Farmer John's N cows (1 ≤ N ≤50,000) always line up in the same order. one day Farmer John decides to organize a game of Ultimate Frisbee with some of the cows. to keep things simple, he will take a contiguous

Question: Calculates the number of monotonically dropped tuples. The three elements do not have to be continuous. Ideas: Convert to double reverse order: The line segment tree calculates the reverse order number, and then the reverse order number of

It is also the minimum spanning tree, but s points can be connected among n points. Use krusical. Record the number of edges added each time. When the number of connected edges has n-s, it jumps out.   #include #include #include #include

In a regular expression, the brackets in front [belong to a special character and need to be escaped to match it, that is, \ is added; then the brackets] do not belong to a special character and do not need to be escaped. Var pattern = "(\ [{1})"; //

Background1_problems in Computer Science involve maximizing some measure according to constraints. consider a history exam in which students are asked to put several historical events into chronological order. students who order all the events

You must first select the shortest path. If no Shortest Path is available, that is, several roads are equal, and then take the test. Faster with Dijkstra. Add the corresponding cost when selecting the shortest edge. For details, see the code: #

A tree is given with the point weights. There are three operations: I C1 C2 K: add KD C1 C2 K to all vertices in the C1 and C2 paths: subtract all vertices in the C1 and C2 paths from kq c: query the Weight Analysis of node number C: Typical tree

Idea: rapid matrix Power Analysis: 1 The number of n given by the question is 0 ~ The distance between two numbers is min (| I-j |, n-| I-j | ). Given d and k, each number is converted into a new number after each transformation. This new number is

I was a little excited when I was doing CF for the first time last night, but I was not allowed to submit it when I wanted to submit it. I had to register for the first CF competition. Alas, no culture, really terrible ==|, so I cut down the first

A two-dimensional map is provided. Each point is an obstacle or an open space. A robot has three operations: 1. Move forward; 2. Turn left 90 degrees; 3. Turn right 90 degrees. Given the start point and end point, ask the number of shortest paths

There are five types of coins with a nominal value of 1, 5, 10, 25, and 50 respectively. Now, we provide the amount and ask how many methods can be used to make up the nominal value. Solution: it is the same as uva674, but the upper limit is

When the object name is directly transferred as a function parameter using the object name, a new object will be created during the function call, which is a copy of the object of the form parameter. = ===== # Include using namespace std; class
