What is an algorithm and provide an example of a simple sorting algorithm?

• A. An algorithm is a step-by-step procedure; example: bubble sort, which repeatedly swaps adjacent elements.
• B. An algorithm is a programming language; bubble sort is a compiler.
• C. An algorithm is a hardware circuit; bubble sort is an optimization.
• D. An algorithm is a data type; bubble sort is a data structure.

Answer: (A)

An algorithm is a precise, step-by-step procedure that takes input, performs a finite sequence of instructions, and produces output. It’s a method for solving a problem that is defined independently of any specific programming language or hardware. A simple sorting algorithm illustrates this idea: bubble sort. It works by repeatedly looking at adjacent pairs of elements in the list and swapping them if they are out of order. After each full pass, the largest unsorted element moves to its correct position at the end of the list. The process repeats until no swaps are needed in a pass, at which point the list is sorted. This demonstrates how an algorithm is a clear, repeatable sequence of actions to achieve a goal. The other descriptions mix up different concepts: a programming language is a way to express algorithms, a hardware circuit is a physical implementation, and a data type is a kind of value. Bubble sort is an example of a simple sorting algorithm, independent of language or hardware.
