Bitwise Algorithms - Basic Practice Problems

Bitwise algorithms are a category of algorithms that operate on individual bits within a data unit, rather than the entire data unit itself. They leverage bitwise operators, which are special operators designed to perform operations on bits. Common bitwise operators include AND (&), OR (|), XOR (^), and NOT (~). Before diving into the world of

Circular Linked List meaning in DSA

A circular linked list is a special type of linked list in which the last node is connected to the first node, creating a continuous loop. In a circular linked list, each node has a reference to the next node in the sequence, just like in a regular linked list, but the last node's reference points back to the first node. Characteristics of Circular

Queue meaning in DSA

A Queue is defined as a linear data structure that is open at both ends and the operations are performed in the First In First Out (FIFO) order. Characteristics of Queue:The first item added to the queue is the first one to be processed (or can be firstly deleted/removed), and subsequent items are processed in the order they were added.Enqueue and

Subarray meaning in DSA

A subarray is a portion of an array that consists of consecutive elements from the original array. Characteristics of a Subarray:Contiguity: The elements in a subarray are contiguous, meaning they are consecutive and in order in the original array.Length: The length of a subarray can be any positive integer, from 1 to the length of the original arr

Disjoint Set meaning and definition in DSA

What is Greedy Algorithm in DSA?

A Greedy Algorithm is defined as a problem-solving strategy that makes the locally optimal choice at each step of the algorithm, with the hope that this will lead to a globally optimal solution. In other words, a greedy algorithm always chooses the option that seems the best at the moment, without considering the future consequences or possibilitie
