The origin of the Kodori tree? The original name of Kodori tree is Old Driver Tree (ODT), which is a data structure proposed by a CF competition in 2017, because the title background protagonist is "what are you doing at the end of the day? Are you free? Can you save it?" The protagonist of the data structure is cordolly, so the data ...

School of magic Title Description: Yako likes to collect visible characters without spaces (ASCII code is 33 ~ 126). In her eyes, the value of a character is its ASCII code size, such as the value of 'a' is 97. So far, she has collected n visible characters excluding spaces, and the ith character is Si. But she wanted to maximize the val ...

Construct an empty stack S and allocate memory space.Destroy & stack: destroy stack. Destroy and free the memory space occupied by stack S.Push & S, X: enter the stack. If ...

preface My story with topological sorting The first contact was the class of data structure. However, I was addicted to playing games and didn't understand the code at that time. The second time was the punch in group. The second question of a force deduction fortnightly competition was topological sorting (I used violence to cycle 100 times ...

Let's start with sequence traversal. This is a common problem. Print it according to each layer, as follows: For Recommendation in Deep learning QQ Group 277356808 For deep learning QQ Second Group 629530787 I'm here waiting for you 1 - sequence traversal and deformation Sequence traversal is the most intuitive and simplest sequence, that ...

1. Basic introduction of figure 1.1 definition of drawing A graph is a data structure in which a node can have zero or more adjacent elements. The connection between two nodes is called an edge. Nodes can also be called vertices. Undirected graph: the connection between vertices has no direction, such as A-B, that is, a - > b or B - ...

data structure Main contents: Introduction to data structure linear structure tree structure Introduction to data structure 1 what is a data structure In short, a data structure is a container that stores data in a specific layout. This "layout" determines that a data structure is efficient for some operations and inefficient for ...

1. Basic concepts of sorting Sorting is an operation often carried out in the computer. Its purpose is to adjust a group of "unordered" record sequences to "ordered" record sequences. The purpose of sorting is to facilitate searching. If the whole sorting process can be completed without accessing external memory, th ...

1. Basic concepts of search Lookup table A lookup table is a collection of data elements (or records) of the same type. keyword A keyword is the value of a data item in a data element (or record), which can be used to identify a data element (or record). If this keyword can uniquely identify a record, it is called the primary keyword ...
