1. Stack 1.1 concept Stack: a special linear table that allows insertion and deletion of elements only at a fixed end. One end for data insertion and deletion is called the top of the stack, and the other end is called the bottom of the stack. The data elements in the stack follow the principle of Last In First Out LIFO (Last In First Out ...

Chapter 2 sparse arrays and queues 2.1 sparse array 2.1.1 basic introduction When most elements in an array are 0 or the same value array, sparse array can be used to save the array (compress redundant data) Representation of sparse array: How many rows and columns are there in the first row? How many different values are there (relati ...

background In performance test, sometimes an API request can only be processed once for the same data (such as user registration), or can only be executed sequentially. Multiple users are not allowed to operate on the data at the same time. Different data can be requested concurrently. Therefore, data sampling needs to be handled to avoid mult ...

1. Preface Previous: https://blog.csdn.net/ylc0919/article/details/111050124 It's been ten months since I said I would send the second generation framework. It's hard to have time to summarize the harvest during this period. After writing the first generation AT queue, I have many ideas. For example, can one AT queue manage multiple AT mod ...
