Question: 1 / 400

What is the output of the provided Fibonacci code that iterates ten times?

1,1,1,1,1,1,1,1,1,1,

The correct output of the Fibonacci code that iterates ten times would indeed align more closely with the second choice, which displays the Fibonacci sequence correctly. The Fibonacci sequence is generated by adding the two preceding numbers in the sequence, starting with 0 and 1. Hence, the first ten outputs of the Fibonacci sequence are:

1. 0 (first term)

2. 1 (second term)

3. 1 (0 + 1)

4. 2 (1 + 1)

5. 3 (1 + 2)

6. 5 (2 + 3)

7. 8 (3 + 5)

8. 13 (5 + 8)

9. 21 (8 + 13)

10. 34 (13 + 21)

This sequence illustrates how each number is the sum of the two preceding ones. Therefore, the correct output for ten iterations would display these specific values as intended.

The first choice, which claims the output would be a repetition of '1', does not accurately represent the Fibonacci sequence. Similarly, the third option presents a simple count from 1 to 10, neglecting the additive nature of the Fibonacci calculation. The fourth option mimics the beginning of the
