Quicksort is an improvement of bubble sort algorithm. 1. Sorting process The quick sort algorithm realizes sorting through multiple comparisons and exchanges. The sorting process is as follows: (1) First, set a boundary value, and divide the array into left and right parts through the boundary value. (2) Collect data greater than or equal ...

Preparatory knowledge Heap sort Heap sort is a sort algorithm designed by using the data structure of heap. Heap sort is a selective sort. Its worst, best, average time complexity is O(nlogn), and it is also an unstable sort. First, simply understand the lower heap structure. heap Heap is a complete binary tree with the following pro ...

In fact, the problem is not difficult to understand: The n queen problem studies how to place n ...

LinkedBlockingQueue Blocking queue is one of the common implementations of BlockingQueue interface. It is an optional (queue length can be manually specified) bounded blocking queue based on linked list public class LinkedBlockingQueue<E> extends AbstractQueue<E> implements BlockingQueue<E>, java.io.Serializable { ...

1. Contents and requirements of the experiment: 1. Create two ordered linear tables from keyboard input (input data of each linear table is entered in order from smallest to largest, regardless of sorting algorithm); Output the two ordered linear tables; Merge the two ordered linear tables into an ordered linear table. The output is a merged o ...

LinkedBlockingDeque The LinkedBlockingDeque class implements the BlockingDeque interface. Read the BlockingDeque text for more information about. Deque comes from the word "double ended queue". Deque is a queue where you can insert and delete elements at both ends of the queue. LinkedBlockingDeque is a Deque. If a thread tries to g ...

github address: GitHub - hlccd/goSTL  Comparator summary For some data structures with size comparison, it is very cumbersome to implement some size comparison every time. Especially for some officially set types, it will be simple to implement the comparison of their elements when introducing basic types into the data structure. At the s ...

preface Hello, guys. In the previous article, we shared the Map data structure in ES6 in detail. This article will make a supplement to Map on the basis of the previous article. There is another knowledge about Map that has not been shared, that is, the mutual conversion between Map and other types. Through the study of the previous artic ...

1. Tuples What is tuple Tuple: One of Python's built-in data structures is an immutable sequence Example: t = ( 'python' , 'hello' , 90 ) Variable and Invariant Sequences Invariant sequence: string, tuple No add, delete, change operations for immutable sequences Variable sequence: list, bullet, set Variable sequences c ...

Give you a binary tree and two nodes in the binary tree, and find the nearest common ancestor of the two nodes. Nearest common ancestor: "for two nodes p and q with root tree root, the nearest common ancestor is expressed as a node a, which satisfies that a is the ancestor of p and q, and the depth of a is as large as possible (a node can ...
