Since algorithms are like recipes or plans, we need special ways to show their steps clearly.

Just like a good recipe helps you bake a delicious cake every time, a good algorithm helps a computer solve a problem efficiently and correctly. Here are the main things that make an algorithm good: '''1. Correctness:''' The most important thing is that an algorithm must be '''correct'''.

An algorithm is a well-defined, step-by-step procedure for solving a problem or accomplishing a task. It's a sequence of unambiguous instructions that, when executed, produces a desired output within a finite amount of time. Understanding algorithms is fundamental to programming and problem-solving in computing, as they provide the logical blueprints for software and syst..." current Tag: Visual edit
