I am having trouble with an assignment in computer science. The teacher wants us to Write a program with a loop that asks the user to enter a series of positive numbers (using input validation). The user should enter a negative number to signal the end of the series. After all the positive numbers have been entered, the program should display the largest and smallest of the numbers entered. I don't think we are allowed to use any lists as we have not got to that part yet. The code I have so far is : positive_number = int(input("Please enter a positive number:")) while positive_number >= 0: positive_number = int(input("Please enter a positive number:")) if positive_number < 0: break
