Foreword: in the last article, we learned the sequence table and found that we have a certain grasp of the concept of the sequence table, but after learning the sequence table, we found that there are some places that we can't do better or difficult to do, so we have a linked list. This article will take you into the study of the linked list! ...

I will go against my instinct, disobey my nature and love you forever. Let's summarize the sorting (left over from the last lesson) 1, Stability of sorting (02:56) The same values in the sorting process are sorted by the sorting algorithm, and their relative order remains unchanged. (for the simple basic type array, it is of little use. It do ...

Before thinking about the specific flow of the algorithm, you need to summarize the types of differences. Difference Type If there are two commit commits, Parent, let's ...

Bucket sorting: The sorting under the bucket sorting idea is not based on comparison, and the application range is limited. The data status of the sample needs to meet the bucket division. The following describes the two sorting methods under the bucket sorting idea (1) Count sort (2) cardinality sort Time complexity O(N) Count so ...

Hamiltonian problem and Hamiltonian ring In 1859, the Irish mathematician Hamilton proposed the following game to travel around the world: London, Paris, Moscow and other world-famous cities were marked on the 20 vertices of the regular dodecahedron, and the edges of the regular dodecahedron represent the routes connecting these cities.
