4

3

This function does not give an output.

Question 46 (1 point)

What is the runtime complexity of this function?

Question 46 options:

O(N)

O(N^2)

O(1)

O(log N)

n = 0

n = 2

n = 1

n = -10

Explanation / Answer

Question 44 What values of n will give the base case of the given function?

n = 0

Question 45 What is the output of f(3)

f(3) calls f(2) , f(2) calls f(1) , f1 calls f(0) which returns 2.

2

Question 46 What is the runtime complexity of this function?

O(N)

f(n) calls f(n-1) , f(n-1) calls f(n-2) so on until f(0) which returns 2. 0 to n is (n+1) times . The constant is neglected. Therefore O(n).
