What is generics As a literal meaning, a generalized type means that a specific type cannot be determined during encoding. A placeholder (uppercase, English is recommended) needs to be used first. When running, a specific type is passed in to replace this generic tag Why do I need generics Pseudo demand Suppose we need a list to store Strin ...

1. Implement stack with queue graphic Since two queues are used to implement the stack, it must be related to the nature of the queue. It must be changed back and forth. Let's take a look at this process. code implementation typedef struct { Queue* q1; Queue* q2; } MyStack; /** Initialize your data structure here. */ M ...

Write before In fact, you've updated a note about the balanced tree before;-> Note links; Learn Data Structure Notes (12) [Balanced Binary Search Tree (AVLTREE)] The previous implementation required the index of the parent node of the current node to be calculated;... The steps for the implementation of left-handed and right-handed are ...

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 ...

Catalogue of series articles preface 1, Associative container In the initial stage, we have touched some containers in STL, such as vector, list, deque and forward_list(C++11), etc. these containers are collectively referred to as sequential containers, because their bottom layer is a linear sequence data structure, in which th ...

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 ...

How search works Find concepts Let the record table L = (R1,R2,R3... Rn), where R (1 < = I < = n) is the record. For a given value k, the process of determining the record with key=k in Table L is called search.If there is a record Ri with key=k in the table, it is recorded as Ri key=k, the search succeeds, and the sequence number i (or ...

1, Linear table A linear table is a finite sequence of n data elements with the same characteristics. Common linear tables are: Sequential list, linked list, stack, queue, string The logic of a linear table is a linear structure, that is, a continuous line. However, the physical structure is not necessarily continuous. When a linea ...

Data structure and algorithm learning notes (C language) Circular linked list 1. Definition: circular linked list is another form of linked storage structure. Its feature is that the pointer field of the last node in the table points to the head node, and the whole linked list forms a ring. If the circular linked list is an empty list, the ne ...
