What is an algorithm?

Algorithm is a step-by-step procedure for solving a problem or accomplishing a task. In the context of data structures and algorithms, it is a set of well-defined instructions for performing a specific computational task. Algorithms are fundamental to computer science and play a very important role in designing efficient solutions for various problems. Understanding algorithms is essential for anyone interested in mastering data structures and algorithms.

Algorithms can be divided in:

search

Search algorithms are methods used to find specific items within a data structure, such as an array, list, or tree. They are fundamental in computer science and are used in a wide range of applications, from databases to artificial intelligence.

sort

Sorting algorithms are methods used to arrange elements in a specific order (e.g., ascending or descending). They are essential for organizing data, improving search efficiency, and solving problems like finding duplicates or computing statistics.
