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

Update value final$\_$num as follows:

If user$\_$input is not divisible by $5,$ subtract user$\_$input from final$\_$num.

Otherwise, add user$\_$input to final$\_$num.

Then, read a value from input as an integer into variable user$\_$input.
