When the following code runs, how many times is the line "x = x * 2" executed?

x = 1
while ( x < 20 ):
    x = x * 2

What is the output when this code executes ?

x = 1
while (x <= 5):
    x + 1
print(x)

What is the output produced when this code executes?

i = 1
while (i <= 7):
    i*= 2
print (i)

Consider the following loop:

j = 10
while j >= 5:
    print("X")
    j=j-1

Which of the following for loops will generate the same output as the loop shown previously?
