Q$2)(30$p$)$ Higher$-$Order Functions: Define a higher$-$order function in

Haskell named applyTwice that takes a function $f$ and a value $x$ as

arguments and applies the function $f$ twice to $x.$ The type signature

of the function should be:

applyTwice :: $(aa)aa$

For example, if the function $f$ is defined as double :: Int $->$ Int

$($doubling a number$),$ then applyTwice double $3$ should return $12.$
