Integer user$\_$in is read from input. Write a while loop that iterates until user$\_$in is negative. In each iteration:

Update value output$\_$num as follows:

If user$\_$in is even, output 'win' and increment output$\_$num.

Otherwise, output 'lose' and do not update output$\_$num.

Then, read the next integer from input into variable user$\_$in$.$

Ex: If the input is:

$5$

$6$

$2$

$-9$

then the output is:

lose

win

win

Output number is $2$
