preface This article is on the album: http://dwz.win/HjK , click to unlock more knowledge of data structures and algorithms. Hello, this is tongge. In the last section, we learned how to build a high-performance queue in Java, which involves a lot of low-level knowledge. I don’t know how much you get?! In this section, I […]

It is only a queue with both front-end and back-end supporting insert and delete operations, which is more practical. Therefore, there is no such statement as FIFO. We can do this through arrays, […]

The elements […]

Linked list Summary:1. The time complexity of adding, deleting and searching elements in the head of the linked list is O (1). If it is in other positions, the time complexity of the above operations is O (n).2. The efficient operation of the head element of the linked list meets the requirements of stack construction.

1. Definition of chain storage In order to represent the logical relationship between each data element AI and its direct successor AI + 1, for data element AI, in addition to its own information, it also needs to store an information indicating its direct successor. We call the domain where the data element information is […]
