Problem
Find suitable black-box test data for each of the following:
(a) A function that returns the largest of its three parameters, which are floating-point numbers.
(b) A function that returns the square root of a floating-point number.
(c) A function that returns the least common multiple of its two parameters, which must be positive integers. (The least common multiple is the smallest integer that is a multiple of both parameters. Examples: The least common multiple of 4 and 6 is 12, of 3 and 9 is 9, and of 5 and 7 is 35.)
(d) A function that sorts three integers, given as its parameters, into ascending order.
(e) A function that sorts an array a containing n integers indexed from 0 to n - 1 into ascending order, where a and n are both parameters.
