Write a function named minDistance that returns the smallest distance between two nontrivial factors of a number. For example, consider $63.$ Its non$-$trivialfactors are $3,7,9$ and $21.$

Thus minDistance$(63)$ would return $2$ because the smallest distance between any two non$-$trivial

factors is $2(9-7=2).$ As another example, minDistance $(25)$ would return $0$ because $25$ has

only one non$-$trivial factor: $5.$ Thus the smallest distance between any two non$-$trivial factors is $0(5-5=$

$0).$ Note that minDistance$(11)$ would return $-1$ since $11$ has no non$-$trivial factors.

The function signature is

int minDistance$($int n$)$
