I started playing with F#...

I decided to do some Project Euler problems using F#. 

So here is my first one, Problem # 31.  Nothing in this solution really shows off anything special about F# but you have to start somewhere ;)

 

    1: #light

    2:  

    3: let rec combos amt (denoms:int list) = 

    4:     if amt = 0 then 1

    5:     elif denoms.IsEmpty || amt < 0 then 0

    6:     else 

    7:         combos (amt - denoms.Head) denoms + 

    8:         combos amt denoms.Tail

    9:     

   10:     

   11: printf "\n\nThe Anwer is: %i \n" (combos 200 [200;100;50;20;10;5;2;1])
