Question

Without looking at the definitions from the standard prelude, define the higher-order library function curry that converts a function on pairs into a curried function, and, conversely, the function uncurry that converts a curried function with two arguments into a function on pairs. Hint: first write down the types of the two functions.

Step 1

It then returns a curried function that takes two arguments, a and b, and returns a value of type c. Now, let's define the type signature for the uncurry function: Show more…
