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

Update value final$\_$num as follows:

If num$\_$input is divisible by $3,$ subtract num$\_$input from final$\_$num.

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

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

Note: $x\%3==0$ returns True if $x$ is divisible by $3$ python please
