An algorithm is a list of step-by-step ____ for completing a task. Have you ever followed a ____? A recipe is a type of algorithm. It breaks down a big ____, like baking a cake, into a list of small, easy-to-follow instructions. ____ help us solve ____ quickly and ____. If we work out an algorithm for ____ one problem, we can use it over and over on similar problems. ____ can’t think for themselves, so they need algorithms to tell them what to do. Algorithms tell computers ____ to do everything – from running a video game to ____ a document. The great thing about algorithms is that they ____ down difficult problems into easy ____. You can complete the steps without knowing what they’re for or what the problem is. This makes algorithms perfect for ____. The ____ contains hundreds of millions of ____. How are you meant to find the one you’re looking for? Most likely, you use a ____ engine. Search engines, like ____, are websites that help you find ____ online. Once you’ve typed in your search words, the search engine uses an algorithm to scan through millions of websites. The algorithm looks for websites that ____ your search words and then ranks them all in a particular ____. This saves you lots of ____! ____ help us ____ problems quickly and accurately. If we work out an algorithm for solving one ____, we can use it over and over on similar problems. Think about mazes. How do you solve them? Perhaps you ____ your instincts, choosing paths at ____ until you reach the exit. This might work for a simple maze, but what if you were given a larger one, filled with lots of different ____? If you randomly take different turns, you could feel very ____ and confused. If you had an algorithm for solving the maze, you’d find the ____ every time, no matter how hard the ____ was.
