Algorithm

An algorithm is a clear and ordered set of steps or rules designed to solve a problem. After applying decomposition, abstraction, and pattern recognition, an algorithm brings everything together into a sequence of actions that can be followed consistently to reach a solution. Designing an algorithm means defining a method to solve a problem through a well-structured series of instructions. Each step has a purpose, and the order matters.Algorithm design also includes reviewing and analyzing existing algorithms, then improving them to make solutions more efficient and effective.

Why It Matters

It turns ideas and analysis into actionable steps
It ensures solutions can be repeated and followed consistently
It helps improve efficiency and clarity in problem-solving
It allows solutions to be evaluated, tested, and optimized

Example

Think about making fried rice. The steps must be done in a clear and logical order:

Prepare the ingredients
Heat the pan
Cook the ingredients step by step

If the steps are done out of order, the result will not be the same. An algorithm works the same way—it requires a structured and consistent sequence.
