This function takes a pair of integers m and n$,$ and should return True iff one integer is a cube of

the other integer. That is$,$

cube$($m$,$ n$)$

should return True if and only if

$1.$ n $=$ m$3,$ or

$2.$ m $=$ n$3.$

Fill in the definition of cube by replacing the word undefined with appropriate Haskell code.

$($You are allowed to delete the $=$ if you need to$,$ for example, if you want to define cube using

guards.$)$

Hint: Haskell has an exponentiation operator, $**,$ but it uses floating$-$point arithmetic so I

wouldn$$t trust it here. The multiplication operator $*$ works on integers $($as well as floating$-$point

numbers$).$
