Answer 2

The given code snippet is a Python while loop that starts with the variable i initialized to 1. The loop continues as long as i is less than 2 raised to the power of 3. In each iteration, i is doubled. Let's break down the code execution step by step:

1. Initial State:

   • i = 1

2. First Iteration:

   • i < 2 ** 3 is 1 < 8, which is true.
   • Print i (output: 1)
   • Update i = i * 2 (i.e., i = 2)

3. Second Iteration:

   • i < 2 ** 3 is 2 < 8, which is true.
   • Print i (output: 2)
   • Update i = i * 2 (i.e., i = 4)

4. Third Iteration:

   • i < 2 ** 3 is 4 < 8, which is true.
   • Print i (output: 4)
   • Update i = i * 2 (i.e., i = 8)

5. Fourth Iteration:

   • i < 2 ** 3 is 8 < 8, which is false. The loop stops here.

So, the output of the code will be:

1
2
4

After i is doubled to 8, the condition i < 2 ** 3 becomes false, and the loop terminates.
