Let's learn about two very important techniques for exploring data structures like graphs and trees — these are Depth First Search (DFS) and Breadth First Search (BFS). Imagine you're exploring a maze or a network of friends on social media. You want to visit every room or meet every person — how d ...
When we work with PHP and MySQL, we are often tasked with interacting with a database. A database is where we store data, and MySQL is a popular system used to manage this data. PHP is a server-side scripting language that can be used to interact with MySQL databases, meaning it can send commands to ...
Sparse Matrix. Let's break down this concept in simple terms. First, a matrix is just a rectangular arrangement of numbers in rows and columns. Think of it as a table where each cell has a value. You can have a matrix with any number of rows and columns. Now, a sparse matrix is a matrix that has a ...
Bubble Sort algorithm, which is one of the simplest sorting algorithms. Sorting means arranging a list of items in a particular order, such as ascending or descending order. Bubble Sort is a method to sort a list of numbers or elements in an increasing order. Here’s how the algorithm works: 1. You ...
Question : Sort 20,35,40,100,3,10,15 using insertion sort. Show all passes. Insertion Sort, which is a simple sorting algorithm. Imagine you're organizing a row of books on a shelf. You start with one book, and then, for each new book, you find the right position for it by comparing it with the boo ...
Complete Question : Translate infix expression into its equivalent postfix expression: A(B+D)/E - F(G+H/K)** Today, we will learn how to convert an infix expression into a postfix expression. What is an Infix Expression? An infix expression is a mathematical expression where operators are placed ...
A queue is a linear data structure that follows the FIFO (First In, First Out) principle. Think of it like a line of people waiting at a ticket counter: the person who arrives first is served first. However, a normal queue has a limitation—when elements are removed from the front, the space is not r ...
Imagine you have a treasure map! This map is like a 2D array, a grid of numbers. Now, how do you find your treasure? ● Row Major Order: Think of searching row by row. You start at the very top left corner and read across the entire first row. Then, you move down to the second row and read across ag ...
let's dive into the concept of a stack! A stack is a type of data structure that follows a very simple principle called LIFO—Last In, First Out. Imagine a stack of plates in your kitchen. You always place new plates on top, and when you need one, you take the plate from the top of the stack. So, the ...
Primitive Data Structures : These are the most basic types of data structures, the "building blocks" of all other types of data. They hold only one value at a time. Think of them as the most basic, fundamental types of data we can store in a computer. Commonexamples include: ○ Integers: Whole numb ...
Tower of Hanoi, which is a classic problem in computer science and mathematics. The Tower of Hanoi involves three rods and a number of disks of different sizes. The goal is to move all the disks from one rod to another, but there are a few rules we need to follow: 1. Only one disk can be moved at a ...
Let’s dive into the concept of a hash function. Imagine you have a list of your favorite books, and you want to assign a unique number to each book for easy identification and retrieval. This is where a hash function comes in. A hash function is a special type of function that takes some input (oft ...
We’re going to talk about two important concepts in algorithms: time complexity and space complexity. These are measures we use to evaluate the performance of an algorithm, and they're essential when you're choosing or designing algorithms, especially for large datasets. Time Complexity : Time comp ...
Let’s talk about data structures. Imagine you have a messy pile of books, and you need to organize them. How would you do it? You could sort them by title, by author, or by genre. The way you organize the books is like a data structure. In computer science, a data structure is a way to store and or ...
Today, we are going to talk about the <frameset> and <frame> tags in web programming. These are part of HTML and were used in older web design practices to display content in multiple sections of a single web page. What is a <frameset>? Imagine you have a big page, and you want to divid ...
<h2>Explanation:</h2 Today we're going to learn how to write a C program that checks whether a given integer is a prime number or not. To construct a C program that checks whether a given integer is a prime number or not, follow the steps outlined below. We will use a simple method where we check if ...
