Step by Step solution about How to resolve the algorithm Perfect totient numbers step by step in the Miranda programming language
Source code in the miranda programming language
main :: [sys_message]
main = [Stdout (show (take 20 perfect) ++ "\n")]
perfect :: [num]
perfect = [k | k<-[1..]; k = totientsum k]
totientsum :: num->num
totientsum = sum . takewhile (>0) . tl . iterate totient
totient :: num->num
totient n = #[k | k<-[1..n-1]; n $gcd k = 1]
gcd :: num->num->num
gcd a 0 = a
gcd a b = gcd b (a mod b)
