Algorithms → Linked list operations

OTUS, Алгоритм

This article is dedicated to the launch of the course "Algorithms for Developers" from OTUS. I express my gratitude for the support of the resource by this company.

Let's explore what operations can be performed on a linked list.

Two …

Qt → QCheckBox as QTableView delegate

Delegate, qcheckbox, qcheckbox center, QTableView

Good day.
There was a need to use a delegate to display QCheckBox in the table (to select objects from the list for subsequent work with them).
In order to deal with the delegates, I created a small project.
At …

Algorithms → Linked list types - singly linked, doubly linked and circular

Типы связанного списка, алгоритм

There are three common types of linked list.

• Single linked list
• doubly linked list
• Circular linked list

Single linked list

This is the most common. Each node has data and a pointer to the next node.

Where the address of …

Algorithms → Linked list

алгоритм, связанный список, сортировка

In this tutorial, you will learn about the linked list and its applications. You will also learn how to create and perform various linked list operations.

In the Treasure Hunt game, you start by looking for the first clue. When …

Linux → Recursive setting permissions on all directories and files through the terminal

Bash, bash

Note, not to forget, how quickly through the terminal to set recursively 755 access to directories and 644 files.

Sometimes you have to adjust the access rights to files and directories on the server, well, there when updating, moving. And …

Qt → Qt - Undocumented QMake - Copying Files

Qt, undocumented, QMake

Qt is quite a large framework and it constantly introduces functionality, which unfortunately either do not have time to document or forget to document.

For example, besides the QQuickItem documentation, I highly recommend watching the sources, or at least the …

Algorithms → Circular Queue

сортировка, круговая очередь, алгоритмы

The circular queue avoids wasting space in the usual implementation of a queue using arrays.

DeQueue - removing an element from the queue;
FRONT and REAR are two pointers used to keep track of the first and last elements in …

Algorithms → Queue

очередь, сортировка, Queue, алгоритмы

A queue is a useful data structure in programming. Imagine a queue of tickets outside of a movie theater where the first person to enter the queue is the first person to receive a ticket.

The queue follows the First …

Algorithms → Stack

алгоритм, стек, сортировка

Stack concept

The stack is a useful data structure in programming. It's like a stack of plates stacked on top of each other.

Think about what you can do with such a bunch of plates:

• Put a new plate on …

Algorithms → Merge Sort Algorithm

алгоритм, сортировка слиянием, Merge Sort Algorithm, сортировка

Merge sort is a kind of divide and conquer algorithm in computer programming. It is one of the most popular sorting algorithms and a great way to build confidence in building recursive algorithms.

Divide and Conquer Strategy

Using the Divide …

Qt → Undocumented QMake

pro, QMake, Qt

Introduction

Qmake is a very powerful "meta-make" system that can be used to generate makefiles for different compilers and platforms from the same qmake project (.pro) file. Documentation for qmake has improved a lot since Qt3, but some information is …
