GO Classes DPP | GATE DA | Python Programming | Base Return

Answer 1

The function is called as:

r1 = virfib_sq(1)

First, the function prints $\texttt{n}$.

print(n)

Since $\texttt{n = 1}$, Python prints:

1

Then the base case is true:

if n <= 1:
    return n

So the function returns $\texttt{1}$ and stores it in $\texttt{r1}$. But $\texttt{r1}$ is not printed.

Final output:

1
