vector Foreword In the past few days, I have used STL a lot when writing code, and I have also felt the power of STL, so I reviewed the content of STL again, and summarized and extracted some basic things and important content. This is a vector article . C++’s STL provides us with many […]

Insertion and deletion operations of B+Tree in mysql
The query operation of B + Tree is being discussed on the Internet, but I have a question about how the insertion and deletion operations of B + Tree are performed. Before discussing this issue, let us first talk about a concept, primary key auto-increment, why it is best to set the primary key auto-increment. […]

Six major algorithms: insertion, Hill, selection, heap sort, quick sort, counting sort
1. Insertion sort What is insertion sort, and what is the principle of insertion sort? Insertion sort is just like drawing a card and inserting it into the appropriate position. Principle of code implementation: for (int i = 1; i < n; i + + ) { int end = i – 1; int tmp […]

Introduction: Insertion sorting basically has two steps. First, obtain the insertion position through comparison, then move to vacate the position that needs to be inserted, and finally insert the value. Table of Contents 1. Direct insertion sort 1.1 Introduction: 1.2 Code 2. Half-way insertion sort 2.1 Introduction: 2.2 Code: 3. Hill sorting 3.1 Introduction: 3.2. […]
