Value user$\_$num is read from input. Write a while loop that reads values from input and casts the values into integers, until a positive integer is read. In each iteration:

Update total$\_$sum with the sum of total$\_$sum and user$\_$num.

Read the next integer from input.

The positive integer should not be included in the sum. total$\_$sum $=0$

user$\_$num $=$ int$($input$())$

$\text{'}\text{'}\text{'}$ Your code goes here $\text{'}\text{'}\text{'}$

print$($total$\_$sum$)$
