Problem 1: The Mysterious Function
We have come through an old interesting function whose pseudo-code was defined as
follows:
Algorithm 1 Mysterious-Function(n)
Require: n ∈ Z ∧ n ≤ 222
if n ≥ 222 then
return n − 14
else
return Mysterious-Function(Mysterious-Function(n + 15))
end if
a) Implement the algorithm in Python
b) Try various inputs, within the valid range n ≤ 222, what have you noticed of the
output?
c) Prove your thoughts, hypothesis, in part (b)
[Hint: use your implementation to prove a property of the output at a particular
input along with inductive scheme]
d) Empirically, show the performance curve of the algorithm using time measurements
