I'd be interested in seeing a Cobol solution in one of those videos. We all hear about how horrible Cobol is, but most of us never seen examples as to why.

"Languages should have GCD in the core library" - why? How often does the average programmer use this?

Fortran is great for programming array programs across multiple cores and servers - Julia is the modern alternative.

4:36 Ruby is expression based, the last line will be implicitly returned if you leave off 'return'

Hey Conor! Java could absolutely have a gcd method within java.lang.Math, generics have nothing to do with it, but the other question I have is: Why do you consider gcd an essential function? To me it always appeared as more of a toy for an interesting algorithm but I haven't really seen a use case outside of cryptography (and crypto code is not something one should write themselves unless you really know what you're doing), so I'm curious as to why you have a different view on it.

I'm so glad you were a good sport and gave Fortran a go, it gives a nice contrast to the other languages.

liftM2 takes a function (a -> b -> c) and returns a function (f a -> f b -> f c), (f : Monad) note that you don't need the monad constraint since maximum does not rely on the result of minimum or vice versa - and could just use liftA2 from Control.Applicative - not that it matters in this case but Monad is sequential where as solution using Applicative could be made to be parallell.

or: gcd <$> minimum <*> maximum

Hey! Ruby also has a minmax method, so this is how the ruby solution would look like: nums.minmax.reduce(:gdc). Love your channel! <3

People that requested Fortran wanted to see you suffer :D
