        Headless one-way acyclic linked list: it has a simple structure and is generally not used to store data alone. In fact, it is more used as a substructure of other data structures, such as hash bucket, adjacency table of graph and so on. In addition, this structure appears a lot in the written interview.   &nb ...

Basic concepts A linear table is a finite sequence of n data elements. The elements in the same linear table must have similarityDo not care about the specific data between elements, but about the relationship between elementsLinear table operations: create, judge whether it is empty, determine the length, find, delete and insert Array descrip ...

Enter two linked lists and find their first common node. As shown in the following two linked lists: The intersection begins at node c1. Example 1: Input: intersectVal = 8, listA = [4,1,8,4,5], listB = [5,0,1,8,4,5], skipA = 2, skipB = 3Output: Reference of the node with value = 8Input explanation: the value of intersection no ...

1. Linked list A linked list is usually composed of a series of nodes. Each node contains any instance data and one or two links to the location of the previous or next node. Linked list is a linear list, but it does not store data in linear order, but stores the pointer of the next node in each node. 1.1 classification The node of a single ...

The two-way leading circular linked list is the most complex one in structure, but it also brings advantages that other linked lists do not have because of its complex structure. Today we will introduce the two-way leading circular linked list and complete its construction. 1. What is a two-way cycle linked list? 1.1 one way non leading non c ...

         The previous blog post roughly described the implementation of priority queue. This one will talk about heap and heap sorting. For priority queue, please refer to the following blog post. Detailed explanation of binary heap and implementation of priority queue      &nbsp ...

Tip: after the article is written, the directory can be generated automatically. Please refer to the help document on the right for how to generate it 1, Algorithm implementation 1. Bubble sorting 1) . compare all elements in the sequence in pairs and put the smallest one at the front; 2) . compare all elements in the remaining sequenc ...

Queue is a special linear table and a first in first out (FIFO) data structure. It only allows deletion at the front of the table and insertion at the back of the table. The end that performs the insertion operation is called the tail of the queue, the end that performs the deletion operation is called the head of the queue, and when there are ...

3.1 definition of linear table Definition: a finite sequence of zero or more data elements The first element has no predecessor and the last element has no successor The number of linear table elements n (n > = 0) is defined as the length of the linear table. When n=0, it is an empty table Permutations must be of the same data type In ...
