This section focuses on the source code implementation of the tree structure. First, we will discuss the storage structure of Binary Trees. Binary Tree storage structures include linear storage and chain storage. 1. Ordered storage structure of

This section discusses two interesting data structures: Stack and queue. What is stack, the so-called stack is a linear table with Operations Limited at the end of the table. Because the end of a table needs to be inserted or deleted, it has a

The extension method is actually the syntax feature introduced in C #3.0 (I am out ). By using the extension method, you can add a method to an existing type "dynamic" without creating a new derived type or modifying the source code of the original

First, define the swap method used in the sorting process to exchange the values of two integers: /// /// Exchange the values of two integers/// /// count 1 /// count 2 Private Static void swap (ref int AA, ref int bb){Int temp;Temp = BB;BB =
