  • System analysis – Business Process Modeling

    Time:2022-2-7

    Business process modeling (BMP)BMP consists of three elements: entity, object and activity. Business processes occur between entities. They can be between enterprises, between functions, or between people.BPM is divided into three levels. The first layer is mainly model elements, namely objectives, knowledge and data. The second layer is mainly the construction of the model, specifically […]

  • Common sorting algorithm (C implementation)

    Time:2022-2-1

    Original address: https://www.runoob.com/cprogramming/c-sort-algorithm.html 1. Bubble sorting Bubble sort is a simple sort algorithm. It repeatedly visits the sequence to be sorted, compares two elements at a time, and exchanges them if their order (e.g. from large to small and from a to Z) is wrong. Process demonstration: #include <stdio.h> void bubble_sort(int arr[], int len) { […]

  • How to improve the performance of c# StringBuilder

    This article explores best practices for using c# StringBuilder to reduce memory allocation and improve the performance of string operations. Yes Net, strings are immutable types. Whenever you are Net, a new string object will be created in memory to save the new data. In contrast, the StringBuilder object represents a variable string and dynamically […]

  • Question 26: how to understand quick sort?

    Time:2021-12-19

    What is quick sort? Randomly find a number (called the reference element) in a sequence, and then put the number smaller than the reference element on the left and the number larger than the reference element on the right. In this way, a sequence is divided into two subsequences, and then divide the subsequence into […]

  • Algorithmic journey | quick sorting method

    Time:2021-12-11

    HTML5 school – coder: in previous issues of “journey of algorithms”, we shared bubble sorting and selective sorting, both of which belong to “slow” sorting with time complexity of O (n ^ 2). Today, I share with you a variety of sorting algorithms that are widely used and fast——Quick sort method [average time complexity is […]
