def$$ threaded numbers $($n$)$:

$$Given $$ a $$positive$$integer $$n$,$ return $$a$$ list with numbers $$from$-1$to$-$n$-$with

$$the$$following$$ constraint:

$$ Use $2$ threads, $$ one $$ that $$ produces $$ the $$ even $$ numbers $$ and $$ another $$ thread that

$$ produces $$ the $$ odd $$ numbers.

$$ Grading:

$..-$Do $$ not $$ perform$$any$$sorting$,$ merging, $$ or $$ indexed list$$ insertion$-$to$-$ensure$-$ordering

$$of $$ the output. $$ The $$ threads $$ must $$ cooperate $$to$$ produce $$ the $$ output $-$in$-$order

$$ by $$ appending $$ one $$ element $$ at $$time $$ to $$a$$ shared list$$object$.$ They $$ cannot$$

operate

$$independendently$.$

$-$ The $$function $$ should work$$for $$ an $$arbitrary $$positive integer$$ input.

$$ See$-$test$\_$threaded$\_$numbers$\_$example $$ for $$ an $$ example $$ of $$ how$-$your $$ code

$$will $$ be$$executed$.$
