Four process scheduling algorithms for operating systems (c language)
Table of Contents FCFS SJF HPF RR FCFS FCFS (First-Come, First-Served) scheduling algorithm is the simplest process scheduling algorithm, also known as first-come, first-served algorithm. In this algorithm, processes are executed in the order in which they arrive on the ready queue, that is, processes that arrive first are executed first, and processes that arrive […]
Wen Xin Yi Yan VS iFlytek Spark VS chatgpt (133) — Introduction to Algorithms 11.2 5 questions
5. Using Go language, assume that a set with n keywords is stored in a hash table of size m. Try to explain that if these keywords all originate from the universe U, and |U|>nm, then there is a subset of size n in U, which consists of all keywords hashed to the same slot, […]

4. Using Go language, explain how to allocate and release the storage space occupied by elements by linking all unoccupied slots into a free linked list inside the hash table. It is assumed that a slot can store a flag, an element plus one or two pointers. All dictionary and free linked list operations should […]
“Data Structure, Algorithm and Application C++ Language Description” – Code to implement key-value ordered linked list jump list
Skip list Definition Searching in a dictionary of n number pairs described by an ordered linked list requires at most n key comparisons. If a pointer is added to the middle node of the linked list, the number of comparisons can be reduced to n/2 + 1. At this time, in order to find a […]
Discuss in detail the difference between the sliding window algorithm and the KMP algorithm and the scenarios in which they are used.
What is the sliding window algorithm The sliding window algorithm is an algorithm for solving subarray (or substring) problems within an array (or string). The algorithm works by maintaining a fixed-size window (usually two pointers) that slides over the array to find subarrays that match specific criteria. The basic idea of the algorithm is to […]
Golang standard library: sort package – sorting algorithm
3.1 sort – sorting algorithm This package implements four basic sorting algorithms: insertion sort, merge sort, heap sort, and quick sort. But these four sorting methods are not public, they are only used internally by the sort package. Therefore, when sorting a data set, you do not need to consider which sorting method should be […]
Three basic algorithms for sorting with time complexity n^2
Foreword: Bubble sort, selection sort, and insertion sort are all sorting algorithms with a time complexity of n^2. They are also the basis for us to learn other sorting algorithms later. Next, I will explain these three sorting algorithms to you in as much detail as possible. Time and optimization plan, if you have gained […]

C++ algorithm: shortest string containing three strings
Involving knowledge points Sorted set string Title You are given three strings a, b and c. Your task is to find the string with the shortest length, and these three strings are all its substrings. If there are multiple such strings, please return the one with the smallest lexicographic order. Please return a string that […]
