URL: https://www.progressiverobot.com/merge-sort-algorithm-java-c-python/ Merge sort is one of the most efficient sorting algorithms. It works on the principle of Divide and Conquer based on the idea of breaking down a list into several sub-lists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list. Merge […]
URL: https://www.progressiverobot.com/min-heap-binary-tree/ A Min Heap Binary Tree is a Binary Tree where the root node has the minimum key in the tree. The above definition holds true for all sub-trees in the tree. This is called the Min Heap property. Almost every node other than the last two layers must have two children. That is, […]

What is Backtracking? In backtracking, we start with one possible move out of many available moves. We then try to solve the problem. If we are able to solve the problem with the […]
Learn how to implement a queue in C using arrays and linked lists. Includes step-by-step code, enqueue/dequeue operations, and practical examples.
URL: https://www.progressiverobot.com/reverse-a-linked-list/ Reversing a Linked List is an interesting problem in data structure and algorithms. In this tutorial, we'll be discussing the various algorithms to reverse a [Linked List](/community/tutorials/java-linkedlist-linkedlist-java) and then implement them using Java. Reverse a Linked List LinkedList is a data structure which stores the data in a linear way. Though not in […]
Learn how to implement a stack in C programming using arrays or linked lists. Step-by-step guide with code, functions, and memory management tips
In case of binary trees, if the trees are skewed, they become computationally inefficient to perform operations on. This is the motivation behind making sure that trees are not skewed. Hence the need for balanced binary trees. What is a Balanced Binary Tree Balanced Binary trees are computationally efficient to perform operations on. A balanced […]
URL: https://www.progressiverobot.com/tower-of-hanoi/ The Tower of Hanoi is a classic problem in the world of programming. The problem setup consists of three rods/pegs and n disks. The disks can be moved from one peg to another. The n disks are of different sizes. Initially all the disks are stacked on the first tower. The disks are […]
