The concept of sorting: Sort: The so-called sorting is the operation of arranging a string of records in increasing or decreasing order according to the size of one or some keywords in it.Stability: Assume that there are multiple records with the same keyword in the record sequence to be sorted. If sorted, the relative order […]

4. (C++) Use redis or MySQL to implement a shooting game ranking system
1. MySQL implementation method Suppose we want to design a ranking system, which must involve two major types of data: weapon data and non-weapon general data. They usually have a common attribute: that is, the primary key is unique, such as the player’s numerical number, usually In MySQL, it is an auto-incrementing unsigned integer field. […]

Rust Algorithm Ranking – Illustration and Code Implementation of Insertion Sort
The writing process of Rust code is slightly different from that of other languages, because its compiler does not allow any unsafe writing methods, so the longest time spent in the code writing process is finding compilation errors. s reason. This also has advantages – after the code is written, the stability is greatly improved! […]
