Question
In this exercise we consider algorithms that return a specific set of possible values.
For each type of algorithm select the minimum number of leaves the decision-tree of a
correct algorithm can have.
(In other words, what is the number of distinct values that can be returned by the algorithm?)
An algorithm that returns any pair of 2 elements from an array with n
