I'm trying to learn F# right now coming from C# and I'm finding it a great difficulty to "reconfigure" my mind to the functional programming mindset. So I'm going to attempt a few Project Euler problems to learn how to code functionally.
Here's my attempt at problem 1, now I'm wondering prorimarily, is this an idiomatic approach?
// Project Euler - Problem 1 // If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. // Find the sum of all the multiples of 3 or 5 below 1000. #light open System let multiples = [for n in 1..1000 do if n % 3 = 0 || n % 5 = 0 then yield n] let sum = List.sum multiples printfn "The sum of all multiples are: %d" sum ignore (Console.ReadKey ())
