The following function reverses a string. Trace through the function and answer the questions below.

def reverse(astring):

revStr = []

i = len(astring)-1

while i >= 0:

revStr.append(astring[i])

i = i - 1

return revStr

print(reverse('quiz 3'))

1. What is the purpose of the loop inside the functions scope and how many iterations does it run for a string of size n? (2 marks)

2. Explain how the append function is used in reversing the string? Can you use the append function to append a character to a string? Why would the string not be reversed if the loop started at 0 and stopped at the last index in the input string astring? (3 marks)

How would you change the code to avoid using append and so that the output is in a string format rather than a list format? What string operators would you use? Whats the order of the steps that you would take to implement a variation of this function? Only explain the steps (you dont have to rewrite the code). (3 marks)
