General classification: Internal sorting The amount of data is small, and all data can be sorted in memory. All sorting in this paper is from small to large 1. Insert sort Insertion sort is one of the simplest sorting methods. In order to ensure the efficiency of random access, insertion sort should use array structure to complete ...

1, Sequential storage of binary tree 1.1 storage mode Use the array to save the binary tree structure, that is, the binary tree is put into the array by sequence traversal. Generally, it is only suitable for representing complete binary trees, because incomplete binary trees will waste space. The main use of this approach is the represe ...
