Counting the number of nodes in a linked list is a fundamental operation that provides insight into the size of the list. Knowing the list size is essential for implementing other operations such as insertion at a specific position, deletion, or validation. Learning both iterative and recursive approaches helps strengthen understanding of linked list traversal, […]

Reversing a linked list is a common operation that flips the order of nodes in the list. This can be useful when the last element needs to be accessed first, when implementing algorithms that require backward traversal, or when demonstrating mastery of dynamic memory and pointers in C. Understanding multiple ways to reverse a list

Searching for an element in a linked list is a fundamental operation used to locate specific data. It is important for tasks such as verifying the presence of an element, updating its value, or performing deletion at a specific position. Learning both iterative and recursive search methods strengthens your understanding of linked list traversal, recursion,

Inserting a node at the beginning of a linked list is one of the simplest and most commonly used operations in linked list management. This operation allows you to quickly add a new element at the front without traversing the entire list. Inserting at the beginning is particularly useful when implementing stacks or when frequent

A linked list is a linear data structure where elements, called nodes, are connected using pointers. Each node contains data and a pointer to the next node in the sequence. Unlike arrays, linked lists do not require contiguous memory, which allows dynamic memory allocation and easy insertion or deletion of elements. Linked lists are fundamental

Inserting a node at any position in a linked list allows you to add elements at precise locations, not just the beginning or end. This operation is essential when maintaining order in a list or implementing advanced structures like priority queues. Understanding how to correctly insert nodes at specific positions strengthens your grasp of dynamic

Inserting a node at the end of a linked list is a common operation that allows adding elements in sequential order. Unlike inserting at the beginning, this operation requires traversal to the last node before adding the new node. Understanding how to append nodes efficiently is crucial for building dynamic lists and other data structures

A deque (double-ended queue) is a linear data structure that allows insertion and deletion of elements from both ends: front and rear. This flexibility makes it more versatile than a standard queue, and deques are widely used in task scheduling, caching, and sliding window algorithms. This article demonstrates array-based and linked-list-based deque implementations in C,

A priority queue is a specialized type of queue in which each element has a priority. Unlike a standard FIFO queue, elements with higher priority are dequeued first. Priority queues are widely used in operating systems for task scheduling, network routing, and algorithms like Dijkstra’s shortest path. This article demonstrates how to implement a simple

A circular queue is an advanced type of queue that efficiently uses memory by connecting the end of the queue back to the beginning. Unlike a linear queue, it avoids wasted space after multiple enqueue and dequeue operations. Circular queues are widely used in buffering, task scheduling, and operating systems. This article demonstrates array-based and
