Algorithm learning Chapter 1 Palindrome number Difficulty: simple Title: Give you an integer X. if x is a palindrome integer, return true; Otherwise, false is returned. Palindromes are integers whose positive (left to right) and reverse (right to left) reads are the same. For example, 121 is a palindrome, not 123. Idea: First convert an int ...

2. Save xiaoha Task: The maze consists of n rows and m columns of cells (n and m are less than or equal to 50), and each cell is either an open space or an obstacle. The task is to help Xiao hum find the shortest path from the beginning of the maze to Xiao ha's location. Pay attention to the obstacles. Of course, Xiao hum can't go out of the ...

Problem Description The maximum frequency stack implements FreqStack, a class that simulates operations similar to the stack's data structure. FreqStack has two functions: push(int x), pushing the integer x onto the stack. pop(), which removes and returns the most frequent elements in the stack. If more than one element is most frequent ...

JavaScript data structure and algorithm (Part 2) In the last article, we learned a lot of data structures, including stack, queue, dictionary, linked list and so on. I hope you can absorb them one by one and we will make progress together. In this article, we will explore the mysteries of trees and graphs, and I will introduce several algorith ...

Write before: Hello, I'm time. What we bring today is the quick sort in the sorting algorithm. I explained it graphically and tried to write it thoroughly. Don't say much, let's go! Mind map: 1. Quick sort concept The records to be arranged are separated into two independent parts by one-time sorting. If the keywords of one part of ...

preface Personal summary: String Learning & summary (mainly the summary template) I haven't painted the topic for a long time. I regret not sticking to it. Now, brush the string & Computational Geometry & DP. For others, such as number theory and graph theory, it's ok to be familiar with that very basic algorithm.Thematic port ...
