1. Delete all nodes in the linked list equal to the given value val. If a node is no longer referred to by Java, it will be automatically deleted The linked list is as follows: The given value is assumed to be 3: Reference code: //Delete all nodes with the value of key public void removeAllKey(int val){ if(this.head == nul ...

Linear table Sequential list and linked list Abstract data structure - data combination and operation set Header node: the first node that does not store data elements First element node: the first node where data elements are stored 1, Definition of linear table A finite sequence of zero or more data elements There is order between elem ...

A Graph is composed of a finite non empty set of vertices and a set of edges between vertices. It is usually expressed as: G(V,E), where g represents a Graph, V is the set of vertices in Graph G, and E is the set of edges in Graph G. Graph is a more complex data structure than linear table and tree. In the graph structure, the relationship bet ...

1. Concept of reactor 1.1 definitions If there is a key set K = {k0, k1, k2,..., kn-1}, all its elements are stored in a one-dimensional array in the order of complete binary tree, and meet the following requirements: ki < = k2i + 1 and Ki < = k2i + 2, it is called small heap (or large heap). The heap with the largest root node i ...

1: Collection overview What is the difference between a set and an array? Array is also a data structure in java. The length of data is fixed and the storage mode is linear. And it can store basic data types and objects. Basic data objects can be processed and stored according to the packing of basic types. Our array is of reference data ...

Summary Traversal: left and right roots first; Middle order traversal: left root right; Post order traversal: left and right roots.If you select a hierarchy to build a tree, you need a chained queue to assist the implementation (specify, don't ask why).The specific operation process of the auxiliary queue (key understanding): the data field p ...
