Running through this problem I also faced the weird situation, so:
Given two maps
(def mario {:color "red" :power 45})

I want the max between both but based on :power key.
It would be something like this.
(max mario luigi)
I expect max return not only 45 bu

The problem is known as Collatz Conjecture (also 3n + 1 conjecture).
Basically given a n number then you apply the following rule.
If n is even then n/2 otherwise 3 * n + 1, you keep applying this until you
reach the number 1.
For instance, starting with *n = 6*, one gets the sequence 6, 3, 10,
