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,
Running through this problem I also faced the weird situation, so:
Given two maps
(def mario {:color "red" :power 45})
(def luigi {:color "green" :power 40})
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
thanks

Hi there,
I have this:
*user=>* (partition-all 5 (range 1 20))
((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19))
And I would like to apply the *pmap* over the partitions, something like:
(the line bellow doesn't work)
*user=>* (pmap + (partition-all 5 (range 1 20)))
*I would like to ha
s you yourself said you can use 'apply' instead of reduce

current license that rule the logo.

I thought clojure always did auto promotion between long and bigdecimal,
but I run repl today and I notice this:
(* 1000 1000 1000 1000 1000 1000 1000) raises overflow
(* 1000M 1000M 1000M 1000M 1000M 1000M 1000M) this is ok
So this was always working that way? or they've changed? (and if yes, wh
