I help clients go faster for less using serverless technologies.
Problem
215 = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.
What is the sum of the digits of the number 21000?
Solution
let number = 2I**1000 let answer = number.ToString() |> Seq.map (fun c -> int32(c.ToString())) |> Seq.sum
