Question
Haskell
Consider the function
f (x:xs) = x
What is its type? (5 points). Note: that "type" has a formal meaning
in Haskell, that is, there is only one correct (and very precise)
answer
Which (standard prelude) library function does "f" (roughly)
correspond to? (5 points)
Hint: put the definition of "f" into a Haskell script and check the
type with the ":type" command, and then run it with GHCi to see how it
behaves,
