A - chessboard problem Put pieces on a chessboard of a given shape (the shape may be irregular), and there is no difference between the pieces. It is required that any two pieces cannot be placed in the same row or column in the chessboard. Please program to solve all feasible placement schemes C for placing k pieces for a chessboard of given ...

Sliding window algorithm:Literally, everyone has seen the window and can open and close the window ×)The window of the sliding window algorithm here is divided into fixed and unfixed. The fixed window is the kind of window seen in life. Imagine a large window, and then the sliding screen window. The screen window here is a fixed sliding w ...

A. Ancient Civilization Title portal I'll give you an array a (decimal) with a length of n,, now ask you to take out an ANS (decimal system),, so that the sum of position differences corresponding to a[i] (binary) and ans (binary) is minimized. Take chestnuts for example: the binary of a[i]=5 is 101, and the binary of ans=10 is 1010. When w ...

If there is no such substring, the algorithm returns an empty string; If such a substring is found, the answer can be considered to be unique. 2, Violent solution 1. Algorithm //Violent solution string fun(string ...

This paper mainly starts with the mathematical principle, and discusses how to make the computer learn the linear regression equation through the known data. Before we go into detail, let's take a look at an example. This is a statistical table about the amount of bank loans. It can be seen that in this example, the bank loan amount is relat ...

There are five commonly used shortest path algorithms in graph theory. They are coming. All the villains are coming 💣 The enemy has five seconds to reach the battlefield~ 💓 On graph theory Graph theory has a long history, but graph theory is an important concern in both company interview and programming competition. Now there may b ...

Catalog C. Division by Two and Permutation A. Plus One on the Subset B. Make AP C. Division by Two and Permutation Topic Description Interpretation Given a n array of size n, you can do something like delete a and put a/2 (rounding down) into the array. We can do this many times and output YES if we can get a full permutation ...

Title (medium) You are visiting a farm where a row of fruit trees are planted from left to right. These trees are represented by an integer array of fruits, where fruits[i] is the fruit species on the ith tree. You want to collect as many fruits as possible. However, the owner of the farm has set some strict rules. You must pick fruit accordi ...

Topic Overview: Title link: Ask me to do the problem Problem 1. Unpassable Violence Algorithms _To be honest, the first thing I thought of was this method, but it would exceed the time limit. _Its idea is simple, two-tier loops find each substring, and then use the stack to determine if each substring is a valid substring, which is simpler ...
