Your friend Aria is complaining that programming seems too complicated. She says, "Why do we need things like sequence, selection, iteration, and variables? It's too much to bother with." Explain to Aria what control structures like sequence, selection, and iteration do and why they are needed. Then tell her why variables are important in programming.

An algorithm is a step by step process that describes how to solve a problem in a way that always gives a correct answer. When there are multiple algorithms for a particular problem (and there often are!), the best algorithm is typically the one that solves it the fastest.

an sequence is:An algorithm is a step-by-step process, and the order of those steps are crucial to ensuring the correctness of an algorithm.

Explanation:

so sequences are the closest to blocks of algorithm
