Algorithms

What is an Algorithm?

An unambiguous set of steps, which when performed correctly by a processor, will result in a process being carried out in a finite time.

For example if you were to explain to someone how to make a cup of coffee you would be defining an algorithm;

1.    boil the water,

2.   place coffee in the cup,

3.   place sugar in the cup,

4.   add the boiling water,

5.   add milk,

6.   stir.

1.       Examine the algorithm above. What two properties of the algorithm enable it to correctly describe the solution to the problem of making a cup of coffee? What is it that makes an algorithm correct?(Hint: what would happen if you swapped step "6" and step "2"?)

Making toast

·        Get the toast.

·        Put the toast in the toaster.

·        Get the toppings.

·        Put the toppings on the toast.

·        Eat it.

Posting a letter.

·        Get a pen and a paper

·        Write the letter.

·        Get an envelop.

·        Put the letter in the envelop.

·        Mail it.

Calling a friend on the phone

·        Dial the number on the mobile phone.

·        Press the call button.

·        And it rings.
