Niuke video summary 5 Binary tree first order, middle order and second order traversal First order traversal: first print the current node, then print the whole left subtree, and then print the right subtree Middle order traversal: first print the left node, then the current node, and then the right node Post order traversal: print the le ...

Seven double pointers 1.1 Foundation Collision pointer: refers to two pointers, left and right, pointing to the first element and the last element of the sequence respectively, and then the left pointer increases and the right decreases until the values of the two pointers Collide (i.e. left == right), or meet other special conditions. ...

Josephu Joseph Ring – the leading out of one-way ring linked list Josephu's problem is: let n people with numbers 1, 2,... N sit around. It is agreed that the person with number k (1 < = k < = n) will count from 1, and the person who counts to m will be listed. Its next person will count from 1, and the person who counts to m will ...

plist https://elixir.bootlin.com/linux/v4.9.59/source/include/linux/plist.h#L212 *Descending priority sorted double linked list plist is a list of nodes sorted by priority; The priority of each node is from INT_MIN to INT_MAX (minimum). The time complexity of inserting is O(k), the time complexity of deleting is O(1), and the time complexit ...

876. Intermediate node of linked list Title Description Given a non empty single linked list with head node, return the intermediate node of the linked list. If there are two intermediate nodes, the second intermediate node is returned. Sample Input:[1,2,3,4,5] Output:[3,4,5] Explanation: the returned node value is 3 (The serializatio ...

1, Definition (logical structure) and basic operation (operation) of linear table Definition: a linear table is a finite sequence of n (n > = 0) data elements with the same data type, where n is the table length. When n = 0, the linear table is an empty table. If L is used to name the linear table, it is generally expressed as L = (a1 , a2 ...

1. General Reprint: Manual of facial classics Chapter 8 "LinkedList inserts faster than ArrayList? Are you sure?" 2. Data structure Linked + List = linked list + list = linked list LinkedList is implemented based on linked list. Data nodes are interspersed by two-way chains next and prev. Therefore, when inserting data, you do ...
