What are Catalan numbers? To put it shortly, Catalan numbers is a sequence of infinite numbers with its own property. In mathematics, we have different sequence of number patterns that we’ve all have come across. Of course no other sequence would be possible with out our basic counting numbers sequence(1,2,3,4,5…)…

This week will take a look at a popular leetcode problem and try to solve it with a data structure that we are familiar with. This question is extremely relevant to every day coding. Anyone who has touched a code editor knows the frustration and the feeling of missing a…

On one of my previous posts, we dived in to the topic of asynchronous vs synchronous. This week, we’ll look at a few other core topics and refresh our knowledge of Javascript. Classes & Object According to MDN Web Docs, classes are are a template for creating objects. They encapsulate data with code…

Palindromes | semordnilaP Going through algorithms and practice questions, we all have come across a palindrome or two. If you haven’t, you will run in to one soon. So what is a palindrome you ask? A palindrome is a word, phrase, number or a sequence of characters that reads the same backward or…

Do you have a need for speed? Do you want to do a search and get the answer right here? Right now? If you do, then hash maps are for you because they have a time complexity of O(1). Before we dig any deeper, you should know the HashMap data…

In a previous blog, I went over a coding challenge where we were searching for the closest value in a binary search tree (BST). But now we will go through a binary search tree and see how we can insert and search from a tree. To start off lets explain…

As a software engineer, one concept you need to understand is the difference between synchronous and asynchronous code. As the name implies, synchronous code is sequential, or one at a time. Each line of code is dependent on the completion of the previous line above and doesn’t get performed until…

This week let us take a step up and learn about the Binary Search Tree, also known as the BST in abbreviation. If you haven’t read up on binary search and how to setup a binary search tree yet, I highly suggest you to get familiar with that first before…

As a programmer or even as someone who is starting off learning how to write code, the concept of OOP is a very big concept you will have to learn. Often times, as a new programmer or engineering student, you hear the term OOP (O O P, not oops) but…
