Basic data structure 1. Linear structure Definition of linear structure: linear structure is a set of ordered data items, in which each data item has a unique precursor and successor Except for the first one, there is no precursor, and the last one has no successor When a new data item is added to the data set, it will only be added to t ...

Self-Improvement Money is not life's report card. Money cannot be used to measure whether life is wonderful or not. Common algorithms The following figure shows the sorting process of common sorting algorithms under the four types of input data of "random disorder", "near order", "complete reverse order&quot ...

1. (1): write a program to establish a single linked list and output all data elements in the single linked list one by one. Implementation code: #include <stdio.h> #include <stdlib.h> typedef struct node{ int data; struct node *next; }linklist; linklist *CreateLinklist(){ linklist *head,*p,*s; head = (linklist *)malloc(si ...

preface Hello, I'm long Lu. I'm just a junior now. I'm working on the back end and occasionally on the front end. Now the main language is Java. For a long time before, I was learning some technologies of web development. I haven't studied and brushed questions like data structures and algorithms for a long time. I plan to pick them up and ...

Stack is a common data structure and a linear table with limited operation. Limit linear tables to insert and delete only at the end of the table. This end is called the top of the stack and the other end is called the bottom of the stack. Inserting a new element into a stack is also called stack entry, stack entry or stack pressing. It puts th ...

Abstractqueuedsynchronizer (AQS): The JDK concurrency package (package name: java.util.concurrent, hereinafter referred to as JUC) provides many tool classes for concurrent operations, such as ReentrantLock, CountDownLatch, etc. The foundation of these concurrency utility classes is abstractqueuedsynchronizer *AQS maintains a shared resource ...

1, Algorithm efficiency When we solve problems, there may be a variety of algorithms that are feasible. Which algorithm should we choose? Which algorithm is better? In fact, to measure the quality of an algorithm, we look at the execution efficiency of the algorithm. After the algorithm is written into an executable program, it needs time ...

Get implementation – get the corresponding location element The idea is the same as that of the single linked list! code // 7 get method -- it is not efficient. It can be divided equally. After all, there is a tail node! DoublyLinkedList.prototype.get = function(position){ if(position < 0 || position >= this.length) return ...
