Problem 1 Loops. Read the following code carefully. Note that values of variables start, stop, and step are unknown and marked as "?". You have to answer the following five questions about the code including finding values of the variables start, stop, and step. start, stop, step = ?, ?, ? number 0 for k in range (start, stop, step) : number = k**2 print(number) Question 1 2 pts If the program output is: 1 4 9 how many times did the for loop iterate? 04 O 5 O2 3 O 1 Question 2 2 pts nd If the program output is: 1 4 9 what is the value of the variable stop? 02 O 7 05 06 4 . 8 O 3 Question 3 2 pts If the program output is: 1 4 4 9 what is the value of the variable start? -1 O O2 03 2 O 3 Question 4 2 pts If the program output is: 1 4 9 what is the value of the variable step? o -1 o o 3 O-2 2. Question 5 2 pts If the program output is: 4 25 64 what is the value of the variable stop? 10 O 5 36 100 O 20
