13. Given two strings containing only lowercase letters, calculate the length of the maximum common substring of the two strings. Note: the definition of substring refers to a string formed after deleting some prefixes and suffixes (or not deleted). import java.util.*; public class Main{ public static void main(String[] args) { Sca ...

Learning resources: Pull hook Education What is a ranking problem Sorting - the process of turning a group of unordered data into order. Generally, the order here is from small to large by defaultMeasure the advantages and disadvantages of a sorting algorithm Time complexity - specifically, the best time complexity, the worst time complexi ...

JavaScript data structure and algorithm (IV) queue Cognitive queue Queue is a linear table with limited operation. Its feature is first in first out. (FIFO: First In First Out) Limitations: Deletion is only allowed at the front of the table.Insert operations are only allowed at the back end (rear) of the table. Scenes similar to queue stru ...

Title:   In the old movie "Live and Let Die", there is a plot in which 007 is caught by a drug dealer on an island in the center of an crocodile pool. He uses an extremely bold way to escape - directly stepping on the brain bags of a series of crocodiles in the pool and jumping ashore! (it is said that the stuntman was bitten by ...

1, Foreword The sequential storage structure of linear table (such as array) has continuous storage space, so we don't have to worry about the logical relationship between elements. The biggest advantage of linear table is that it can quickly access the elements at any position in the table. The disadvantage of linear table sequential storage ...

Maximum depth of binary tree Given a binary tree, find its maximum depth. The depth of the binary tree is the number of nodes on the longest path from the root node to the farthest leaf node. explain:   A leaf node is a node that has no children. Example: Given binary tree [3,9,20,null,null,15,7],     3    / \   9  20     /  \    15 ...

Attach the program effect first: Adjacency table: Adjacency matrix, that is, a two-dimensional array is used to store the relationship between each vertex and the corresponding edge. For example, if there are edges between two vertices, set the subscript corresponding to this two-dimensional array to a non-zero value. As shown below: Undirec ...

Recorded on November 28, 2021 Next up was the last blog post on stacks and queues Stack and queue title record (I) 232. Implement queue with stack Idea: this topic is a simulation problem to investigate the understanding of stack and queue. Because the stack is Filo (can only enter and pop up at the top of the stack), and the queue is FIFO ...
