What is your favorite programming language to implement algorithms and data structure?

Or to be more specific, if you write interpreter and compiler, what is your choice of tool?

Ocaml. You cant really beat it in those domains. Close second is C, but i prefer functional.

C#

Has thought of rewriting in F# but since its used in production its not easily substituted.

@Voxera but f# is literally ocaml

@ganjaman I know, but we use a pure .net stack and F# is easier to integrate with the rest.

But probably not, MS is porting more and more of the features into C#.

It might not be fully functional but many if the good parts are there or coming.

And we have more people that can support a C# code base than F#, I think I am the only one who completed an f# program :/

C++ for algo/ds, Haskell for languages (OCaml with LLVM is super nice as well but muh monads).
