Consistency is what transforms average to excellence.
Introduction In this article, we will look at popular greedy algorithms, which are Dijkstra, Kruskal and Prim's Algorithm. Think about how Google Maps finds the shortest path from your home to your fa
Introduction In this article, we will look at fundamentals of linked lists. Linked list is a really powerful data structure especially when you deal with insertion and deletion. Imagine an array with
Introduction In this article, I will be talking about pointers in C. Pointers might be a bit hard concept for beginners, but they are essential to understand what your programs are doing. Moreover, th
Think of yourself building a program. It can be any types, such as website, app, etc. These applications may require database to show the data that the user requested. For example, you can think of a table that stores GPS-related data. The longitude ...
Idea Binary Search is a powerful algorithm to search for a certain value. If you were to find 3 in an array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], how are you going to come up with the index of 3? The first method that pops up in your head would be lookin...
Selection Sort Selection sort is the simplest way to sort an array. Pretend that index 0 is the smallest, and we look at each element. We select the smallest element from other index and swap the two elements. array = [5, 7, 9, 0, 3, 1, 6, 2, 4, 8] ...
In this article, I will introduce the basic concept of Depth-First Search(DFS) and Breadth-First Search(BFS). Both focuses searching, but the difference is the way of doing it. DFS To understand DFS, you need to know stack and recursive function. I ...
Error I was writing a code to crawl a website, and AttributeError: 'NoneType' object has no attribute 'text' occured. My Code: import requests from bs4 import BeautifulSoup param = { 'isDetailSearch': 'N', 'searchGubun': 'true', 'viewYn'...
GIL GIL ensure that only one thread executes Python bytecode at a time, which means it prevents multiple threads from executing Python code concurrently. GIL works like this: There are three threads, but they are not running concurrently. One need...
