Pretty much yeah.. Im going through the book and things like :
Define a function rangeProduct which when given natural numbers m and n,
returns the product m*(m+1)*....*(n-1)*n
I got the solution from my lecture notes but I still dont understand it..
rangeProduct :: Int -> Int -> Int
rangeProduct m n
| m > n = 0
| m == n = m
| otherwise = m * rangeProduct (m+1) n
Totally lost! Haha..
But thanks for the book suggestion, My exam is tommorow so I'm hoping theres
an online version of this book that I can read through!
And maybe by some divine miracle I'll understand it :-)
