Stack push and stack sequence Title Description: Review the basic structure of the stack: The stack structure is first in first out, last in first out Stack in sequence: [1,2,3,4,5] stack out sequence [4,5,3,2,1], does it belong to the same stack in and out sequence? There may be hints in the stack: Idea: Use a stack simulati ...

Pay attention to the official account and exchange with each other. Search by WeChat: Sneak ahead. What is a jump list The balance data structures often used in development include B number, red black number and AVL number. But if you implement one of them, it is very difficult and takes time to implement. The jump linked list is a fast searc ...

Title Description Give you a linked list, delete the penultimate node of the linked list, and return the head node of the linked list. Advanced: can you try using one scan? Example: Input: head = [1,2,3,4,5], n = 2 Output:[1,2,3,5] Input: head = [1], n = 1 Output:[] Input: head = [1,2], n = 1 Output:[1] preface When operating th ...

Linked list and recursion: Last time Algorithm and data structure foundation < 4 > -- dynamic data structure foundation of data structure foundation: linked list < medium > We have made a preliminary study of recursion. At the end of the paper, it is mentioned that we must understand the macro semantics of recursion when writing th ...

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 ...

LinkedList source code analysis 1. Introduction Through the inheritance system, we can see that LinkedList not only implements the List interface, but also implements the Queue and Deque interfaces, so it can be used as a List, a double ended Queue, and of course, a stack.It can be seen from the inheritance system that LinkedList implem ...

Given the head of a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. Return the linked list sorted as well. Example 1: Input: head = [1,2,3,3,4,4,5] Output: [1,2,5] Example 2: Input: head = [1,1,1,2,3] Output: [2,3] Constraints: The number of nodes in the lis ...
