• Y is always less than or equal to X

Looking at this algorithm, which statement is most true?

• One number must be higher than the other for this to run

• The lowest number will be output

• The highest number will be output

• If the numbers are equal, then no number will be output

In relation to algorithms, the term 'accuracy' refers to...

• How often the algorithm produces the correct output from a given set of inputs

• How well an algorithm is written

• Whether the algorithm syntax is correct

• How readable the algorithm is
