3. (20pts): What is the time complexity of the functions below? Time complexity Code a) def test(n): for i in range(n): for j in range(n): print(i, j) b) def test(n): for i in range(n): print(i) for j in range (n): print(j) c) def test(x, y): for i in range(x): print(i) for j in range(y): print(j) d) def test(n): i = n e) while i > 0: i = i // 2 print(i) def test(n): for i in range(n): for i in range(n): for k in range(n): print(i, j, k).
