Chain List Introduction 1.1 Comparison of advantages and disadvantages between order table and chain table Sequence table Advantages: Any element in the table can be accessed at any time; Disadvantages: Insert and delete operations require a large number of elements to be moved. Chain Storage Linear Table Advantages: No storage unit with ...

preface          Infix expression is the expression we often use in addition, subtraction, multiplication and division. Suffix expression is a computer-friendly expression. The computer can use two stacks to calculate the input calculation string Tip: the following is the main content of this ar ...

At this time, there are only two elements in the array, so we only need to constantly compare the sizes of child elements in the two elements to obtain a complete ordered array, as shown in the following figure: This is a complete merging and sorting process. Next, let's implement it with code function mergeSort(arr) { // Combin ...

1, Sequential queue Because the implementation of sequential queue is relatively simple, let's talk about the implementation ideas and some precautions. Sequential storage structure of queue The sequential storage structure of queue is called sequential queue. It uses a group of continuous storage units (one-dimensional array) to sto ...

The penultimate node in the lin k ed list OJ link: https://leetcode-cn.com/problems/lian-biao-zhong-dao-shu-di-kge-jie-dian-lcof/ Title: enter a linked list and output the penultimate node in the linked list. In order to conform to the habit of most people, this question starts from 1, that is, the tail node of the l ...

Introduction It is believed that the little buddies who have programming basics all know the data structure of arrays. It should also be the first data structure that we come into contact with. Those who have learned C or C++ should know that arrays and pointers are closely related. What are the different features of arrays in Java without poi ...

Binary tree Tree: it is a nonlinear table structure with n (n > = 0) nodes. When n=0, it is called an empty tree. In any non empty tree: There is only one root nodeWhen n > 1, the other nodes can be divided into m (M > 0) disjoint finite sets T1,T2,..., Tm. Each set itself is a tree, which is called the subtree of the root Bina ...

The following describes an advanced data structure based on a single-chain table, jump table.  Sort the single-chain list first, then for the ordered list For efficient lookup, jump tables can be used as a data structure. Its basic idea is the idea of dichotomous search. The precondition for jumping tables is In the light of&n ...

1, Title Description Enter two acyclic single linked lists and find their first common node( Note: because the incoming data is a linked list, the prompt of error test data is displayed in other ways to ensure that the incoming data is correct) Example 1 Input: {1,2,3}, {4,5}, {6,7} Return value: {6,7} Note: the first parameter {1,2,3} r ...
