1, Foreword The most important and fundamental aspect of Redis is its rich data structure. The reason why Redis stands out is that it has rich data structure and can support a variety of scenarios. Moreover, Redis's data structure implementation and application scenarios are quite common in the interview. Next, let's talk about Redis's data st ...

This problem requires you to construct a binary tree. The binary search tree is also a complete binary tree, and then print out its sequence traversal sequence ...

2021SC@SDUSC introduction In a oj system, the core content is the judgment part. Whether it is a real user or a question judging machine, to detect whether the code written by the user is correct, you only need to compile the source file where the running code is located, and then compare whether the program output result is the same as the s ...

In C language, we all know about stack and queue. C + + provides a better solution. STL can help developers reduce a lot of work. In other words, some big guys have helped us write these data structures and encapsulated them into a library. For these basic data structures, you can create a data structure object like using int and double. ...

Sequence table Sequential table is a simple linear structure. Logically adjacent data is stored adjacent to each other in the computer. It can quickly locate the number of elements, allow null values in the middle, and move a large number of elements when inserting or deleting. Three elements of a sequence table Use elems to record ...
