The Queue data structure is studied in most Computer Science courses on Data Structure and Algorithms. In this post, you will learn the two main implementations of this important data structure. What is a Queue A queue is a linear data structure that follows the First In First Out (FIFO) principle. This means that the […]

The Stack data structure is studied in most Computer Science courses on Data Structure and Algorithms. In this post, you will learn one C# implementation of this important data structure. What is a Stack A stack is a linear data structure that follows the Last In First Out (LIFO) principle. This means that the last

Command-line arguments are a useful way to gather input for our console application. In this post, I’ll show how to use these types of arguments in your C# console applications. Why use command-line arguments? As you should know by now, algorithms solve a problem by taking input and calculating an output. For instance, you can

A C# Console Menu Application is a great way to start learning programming. With a menu console application, you can easily test your code and see results after giving certain inputs. In this post, I’ll show how to create a C# console menu application. To create a menu for a C# console application, I recommend

Unit tests are a great tool to have in every programmer’s toolbox. In this post, I’ll show an example of how to write a unit test to make sure your code for reading from a text file works properly. Let’s say we have two classes already implemented: Laptop and Lenovo. The class Laptop handle the

In this post, I’ll show a Python program to calculate the reverse of an integer number without using strings. One reason for not using strings is that we want to focus on the algorithm instead of getting a solution we don’t fully understand. The other one is that converting big numbers to strings is a

The Euclidean Algorithm to calculate the greatest common divisor (GCD) has many applications. We use it in programming class for two reasons: to practice loops and recursion, and to promote algorithmic thinking. In this post, I’ll give you a description of the algorithm, as well as a few different implementations for you to practice loops

Creating a python program to print the factors of a number is another good exercise to keep practicing loops in any programming language. If you divide a number by a second number and you get as remainder 0, then the second number is a factor of the first one. For instance, 2 is a factor

Let’s examine how to determine whether a word or sentence is palindrome or not in python. Words and/or sentences are palindrome when you can read them from beginning to end and vice versa and have the same meaning. In the case of sentences, we don’t consider the spaces and punctuation. Some examples are: Civic Radar
