Can you explain what is meant by an algorithm in the context of programming?

An algorithm in programming is a clearly defined sequence of steps or instructions that must be followed to solve a specific problem or achieve a result.

Example: a sorting algorithm for a list of numbers is a set of rules by which the program arranges the elements in ascending or descending order.

A simple sorting algorithm in Python:

numbers = [5, 2, 9, 1]
numbers.sort()  # built-in sorting method
print(numbers)  # [1, 2, 5, 9]

Algorithms are important because they allow formalizing the solution to a problem and making it reproducible and understandable for a computer.
