Algorithms

An algorithm is a step-by-step procedure or step-by-step instructions for solving a problem or completing a task.

Characteristics of Good Algorithms

1. Input - Accepts zero or one or more inputs.
2. Output - Produces at least one output.
3. Finiteness - Terminates after a finite number of steps.
4. Correctness - Produces the correct output for all valid inputs.
5. Definiteness - Each step is clearly and unambiguously defined.
6. Efficiency - Uses minimal time (time complexity) and space (space complexity).
