Violent enumeration $k$, for a substring, calculates its positive hash value and the inverse hash value, taking the minimum value to its final hash.For $k$, there are $\lfloor\frac{n}{k}\rfloor$ substrings, and the number of different substrings can be counted by calculating their final hash value.Time Complexity $o (n\log N) $.#include 　　BZOJ2081: [Poi2010]beads

To give a circular string, ask where to start is the dictionary order of the string is minimal.Idea: The minimum representation and suffix automata, but I was to learn the suffix automata to write this problem, I did not learn the minimum notation.The procedure is simple, first establish a suffix automaton, and then from the root start along the Tranc pointer from the A->Z, the point that arrives at the end of the string is the smallest dictionary order, the starting point as long as the length

POJ 1509 Glass Beads suffix Automatic Machine Give a circular string and ask where the Lexicographic Order of the string is the minimum. Idea: the least representation method and the bare Question of the suffix automatic mechanism. However, I did not learn the least representation method when I wrote this question to learn the suffix automatic mechanism. The procedure is very simple. First, create a suffix automatic machine, and then start from the r

# Include /* Three difficulties: 1) Design a stack structure to meet the following conditions: the time complexity of Min, push, and pop operations is O (1) 3) design a system to deal with word collocation. For example, if Chinese and people can be used together, the Chinese people and China are both effective. Requirements:1) the number of queries per second may exceed;2) the word order is 10 W;3) each word can be combined with up to wordsWhen users enter the Chinese people, they need to re

Q: use k different colors to dye a n-length necklace. Question: 1. Rotation replacement: There are n rotation replacements, which are rotated in sequence: 0, 1, 2, ''' n-1. For each rotation replacement, the number of cyclic factors obtained after cyclic decomposition is gcd (n, I ). 2. Flip replacement: parity. When an odd number is used, the rotation axis is equal to (vertex + link to the Edge End Point). There are n vertices in total, so there are n replications, the number of factors after e

Original question: There is a string of beads (the beginning and the end are not connected), a total of m, each bead has a color, and the total number of colors does not exceed n (n Question Analysis: I. Brute Force Search 1. The simplest method is brute force search. Scanning the nth position one by one starts to contain the shortest color range of n. the time complexity is O (M ^ 2 ). 2. Start scanning from I. Each time a new color appears, t

Question Returns the minimum representation of a string. Analysis Of course, this question can be done in the smallest notation! But I want to learn the suffix! We multiply the length of this string by two, then create Sam, and then run the smallest letter on Sam every time to find the length of N and then stop. If u is stopped, ANS = sT [u].

Given a 10x10 triangle board and 12 kinds of parts, each part can only be placed once, and can be rotated and flipped. Some parts have been placed on the top, and a solution is proposed, place 12 parts on the board without Overlap First of all, this question is about DLX, but it is really disgusting to create a graph. We need to enumerate up to eight orientation positions for each part. At first, I wanted to process all the code, but later I found that I could not do it. So I chose to input all

In retrospect of his meditation experience, Castle Peak said: "When not meditation 30 years ago, see Mountain is mountain, see water is water." And then, having witnessed the knowledge, there was a place in it. See the mountain is not a mountain, see water is not water. Now we have a rest place, according to the

There are many great figures who have summed up the steps for setting confidence in the mountains, which are generally divided into six stages. First, people must have a dream: This is the first step of confidence and prudence. Confidence in mountain migration often begins with a dream. There is no doubt that the biggest energy in the world is a novel idea. There is a saying that a great person can only have a great idea. Confidence begins with an ide

Came to Changsha so many days, except for business trips, most of the time in the company, sister home and Hotel 3.1 line of life, today cooling, longing for a rain did not come, it is a day of wind blowing. After dinner in the evening, it was intended to hike back to the hotel in cool weather, just to relieve the tension of the work. Sister call, Night together to climb Yuelu Mountain, with my idea of walking home coincides with, compared to climb t

This is the fifth time during the weekend's mountain training. This time, only two people were involved because of the temporary tasks of other associates. We decided to go through one of the green fields and capture the mountains from the qianjuntai pit to the qingshuijian, this route is 1.5 in the green field, and should not be difficult (for those people ).Because we heard that there was bus No. 929 heading for qianjuntai pit at a.m., we all arrive

The beauty of Yuelu mountain, words can not be described, ink can not be portrayed.Since September 2014 to South Central South University to study, today nearly two time, climb Yuelu mountain dozens of times. However, I have never met the prosperity of today. Forest, fog diffuse, far from the mountains of white clouds, in which, such as Mu Fairyland. The fog is blowing, the whole body is refreshing, the moo
