Data Structure BASICS (19) and data structure basics 19Full Binary Tree
First, let's review the two properties of the Complete Binary Tree:
Property 1: the depth of a Complete Binary Tree with n nodes is [logn] (rounded down) + 1.
Property 2: If a Complete Binary Tree Containing n nodes is numbered 1 to n from top to bottom and from left to right, any node numbered I in the Complete Binary Tree is:

A chain queue is a storage representation based on a single-chain table. Its shape is shown in:
(The queue head Pointer Points to the first node of the single-chain table, and the tail Pointer Points to the last node of the single-chain table. Note that there is no useless blank [Head/end] node)
The chain queue represented by a single-chain table is par

Cyclic linked list: the pointer of the pointer field of the last node refers to the linked list of the first node;
The difference between a cyclic single-chain table and a single-chain table is that the pointer to the most node in the table is no longer NULL, but instead directed to the header node (so we need to slightly modify our original MyList ),

The basic idea of Merge Sorting:
"Merge" two or more ordered subsequences into an ordered sequence: assuming that the table to be sorted contains n records, it can be considered as n ordered subtables, the length of each sub-table is 1, and then merged into two to obtain [n/2] ordered tables with a length of 2 or 1. Then, merge the quantities ,...., this is r
