This article focuses on the implementation. The first contact with the data structure of jump table was in Redis. At that time, I only learned the theoretical knowledge of jump table, which is difficult to support by theory alone. This can be realized when I was asked about jump table in the process of byte interview Jump table is a very high- ...

Clip - stack   Linear structure stack, very much like a magazine. As we all know, the cartridge on the clip is pressed in from the entrance and taken out from the top when used. So the first bullet pressed in will be used first. The stack is like this. When data enters, it enters from the top of the stack; It is also taken out from the top of ...

Two stacks S1 and S2 are used to simulate a queue. Two stacks S1 and S2 are used to simulate a queue. When an element needs to be inserted into the queue, S1 is used to store the input element, that is, S1 performs the stack operation. When it is necessary to get out of the queue, the stack operation is performed on S2. Since the order of t ...

If you use Python as the language for data processing, pandas is probably one of the most used libraries in your code. The key data structure of pandas is dataframe, which is a spreadsheet like data table composed of rows and columns. When dealing with dataframes, we often need to deal with indexes, which can be tricky. In this article, let's r ...

1.1 basic concepts A binary heap is a complete binary tree (different from a full binary tree). The value of a node in the heap is always not greater than the value of its parent node. Usually, this heap is called the maximum heap (the corresponding minimum heap can be defined). An element in the lower layer is not necessarily smaller than an e ...

1. [problem description] There are n people sitting around a round table. Now start counting from the s person, count to the m person, then start counting again from the next person, and count to the m person again. Repeat until all people are listed. The Josephus problem is: for any given n, m, s, find the sequence table of n people obtained ...

The shortest path problem of a graph Description The weather is getting colder. The old and frail Yueyue bird plans to spend the winter in a city with appropriate temperature in the south. However, due to the serious aging of its wings, the farthest flight distance is limited. Please calculate the shortest distance required for the poor Yueyue ...
