Formula Challenge: Create a guitar fretboard diagram

mtarler

I will try to post a code snippet.

Another place where arguments are read from left to right is Curried functions

= LAMBDA(x,LAMBDA(y,LAMBDA(z, (x+y)/z)))(3)(5)(2) 

gives 
= (3+5)/2 = 4 

or, with naming, 
CurriedLambda 
= LAMBDA(x,LAMBDA(y,LAMBDA(z, (x+y)/z))) 

= CurriedLambda(3)(5)(2) also gives 4 

The final parameter can also be provided by a helper function

= MAP({2;3;4}, CurriedLambda(3)(5)) 

gives 
= {4.00; 2.67; 2.00}
