Sorting algorithms are cool. But, every time I learn or refer to any algorithm in my head or watch a YouTube video, I can understand and recall how it works but, my brain starts yelling – write the code! write the code! If you are trying to learn or understand… Read More »Sorting Algorithms in C++
I had started the #30DaysofCode📚 challenge while I was revising the basic concepts, data structures, and solving easy problems on LeetCode. I documented this so that it helps both me and others to recall what we have learned. How to use this list📑 First, look at the given questions, if… Read More »#30DaysofCode
In programming, Recursion means a function calling itself. The best use of recursion is when we have a big/complex problem and is solved by breaking down the problem into smaller instances. In this post, we’ll see direct and indirect recursion. Types of Recursion Generally, there are two main types of… Read More »Direct & Indirect Recursion
Tree Traversal: visiting every node of a tree. Unlike other linear data structures, where we traverse through every element in order, it’s not the same with the tree. Trees being non-linear data structures, there will always be more than one way to traverse through a tree. There are three types… Read More »Tree Traversals – Preorder, Inorder, Postorder
The Binary Search Algorithm, a simple and faster search. But on one condition, we need a sorted array or sort the given array before we perform a binary search. Why Binary Search? We can use linear search for smaller numbers but, when having hundreds, and thousands, to compare, it would… Read More »Binary Search Algorithm
Yes, we are doing it today. The all-time famous interview question, Do you know how to reverse a Linked List? Well turns out, it isn’t that difficult and it’s all about logic and pointers, okay let’s get started. Alright, I already wrote a post explaining the basic operations and structure… Read More »Reverse a Linked List
