Let's first look at the following two questions: Question 1. Can the key values of the red black tree be repeated? Question 2. Must the red black tree have a key value? There are many introductions about red and black trees on the Internet, and red and black trees are also widely used. Ask Du Niang. She will tell you all kinds of implementati ...

1. Arithmetic Progression of Primes (20 points) In mathematics, an arithmetic progression (AP, equal difference column) is a sequence of numbers such that the difference between the consecutive terms is constant. In 2004, Terence Tao and Ben Green proved that for any positive n ...

Note: all the following contents are from personal superficial understanding of the use of binary search, for personal reference only! Don't spray if you don't like it. Welcome to correct it! 1, The situations suitable for binary search are divided into two categories: 1. Obvious conditions: The array is ordered and clearly tells you that th ...

Linked list Definition of linked list n nodes are linked into a linked list, which is the linked storage structure of linear list. Because each node of this linked list contains only one pointer field, it is called single linked list. 1. Characteristics of linked list Linked list is not suitable for fast positioning data, and is suitab ...

Binary tree (BST) basic traversal -- depth first In many cases, we may need to traverse the tree like traversing an array, so as to take out each element stored in the tree. Because the tree structure is different from the linear structure, it cannot traverse backward from the beginning, so there is a problem of how to traverse, that is, ...
