1. (Please in python!) Write a program, that inputs 3 integer values and calculates and displays their product according to a rule: If one of the values is negative or 0, then it does not count towards the product. The program will stop if all a, b and c are negative.
2. Write a program, Lab02_Q3.py, that inputs a set of characters from the user and forms a string by concatenating only the digits in reverse order. The user will continue inputting until * is entered. Hint: You can invoke the isdigit() function on a character, and it will return True if the string is a digit, False if not. 5.isdigit() -> True.
