Introduction to Programming
A programming language is a set of instructions which is used to create software programs. There are many popular programming languages used around the world such as C, C++, Java, Python and more. Programs are a set of instructions which runs a program to execute a specific task.
Learn Data Structures in programming language which is a method of organising, processing, storing data. Linked List, array, Stacks, Queues, graphs, etc are some of the examples of data structure.
- Array: An array is a collection of elements identified by an index or key. It provides faster access to elements and is fixed in size. An array is a group of similar elements.
- Linked Lists: A sequence of nodes having connection to the next nodes using the reference to the next node.
- Stacks: A collection of elements that follows the Last In, First Out (LIFO) principle. Operations include push (add) and pop (remove).
- Queues: A collection of elements that follows the First In, First Out (FIFO) principle. Operations include enqueue (add) and dequeue (remove).
- Heaps: This is a hierarchical structure connected by edges. Binary Trees, Binary Search Trees, AVL trees are some of the examples of heaps data structure.
- Graphs: It is a collection of nodes and edges interconnected to each other. Directed graphs, undirected graph, and weighted graphs are some of the popular examples.
