The curried version of let f (x,y,z) = (x,(y,z)) is

		let f (x,(y,z)) = (x,(y,z))
		Just f (because f is already curried)
		let f x y z = (x,(y,z))
		let f x y z = x (y z)

Expert Solution

What is Currying?

In mathematics and computer science, currying is the technique of converting a function that takes multiple arguments into a sequence of functions that each take a single argument. For example, currying a function that takes three arguments creates three functions:

For Ex:

Let there be a function which maps as

Currying the above function will produce

Thus maps from to a function which in turn maps from to
The above mathematical expression can also be represented as:

Hence,

Find some more examples below to understand it clearly.

As here, the output is (x,(y,z)), output remains constant while currying.

So, f(x, y, z) becomes f x->y->z-> (x,(y,z))

Ans : Therefore f x y z = (x,(y,z))

Thefore C must be the correct option.
