Why is it important to plan?
An algorithm is a set of instructions that completes a tasks.
We use algorithms all the time, in all parts of our life such as, following recipes, building Lego models, assembling flat-pack furniture or following sat-nav directions.
When creating programs (stored sets of instructions for a computer to follow) it helps to plan your program first, and is essential in bigger programs.
If you don’t plan, you might forget important steps, mix things up, or waste time. But if you plan, you know what to do, when to do it, and how everything fits together. It helps the program work properly and saves time fixing mistakes later.
