Given an input string with the scientific pitch notation for standard tuning ( http://en.wikipedia.org/wiki/Guitar_tunings#Standard_tuning ) of a guitar string (e.g. 'E4'), return the frequency (to nearest whole number) in hertz (in this case, 330).
Many solutions depend on the tested inputs... Is there a way to prevent it ?
I posted 2 working solutions, they're not the shortest, but at least, they work with ANY input (C0, B10...), not just the tested ones!
Almost all working solutions are just a plain lookup tables : boring.
Works for all 70 natural notes between 'C0' (16Hz) and 'B9' (15804Hz)

Only works for tested inputs
tried D6 => 147 instead of 1175
