Triple Accessing Element

Question

If in Haskell I had a tuple:

x = (1, 2)

I could use fst x to retrieve 1 and snd x to retrieve 2

I was wondering, if I had a triple:

y = (1, 2, 3)

is there a similar function I could use?

Answer 1

You need to write your own extractor functions:

extractFirst :: (a, b, c) -> a
extractFirst (a,_,_) = a

The fst and snd functions are only applicable for a tuple i.e (a, b)
