📝 Mock Test 2 (Quiz 2 - Sep 2025)

Question 1

List/Dictionary Expression matching. Accepted Answer: (Option ending with f - (3))

Question 2

Common Elements in List A and B (indices logic). Accepted Answer: [1, 2, 3, 4, 5, 6, ....., 49, 50] (Wait, accepted answer wasn’t explicitly checked in view, re-verifying logic: A reverses N? No, someList recreates it? If someList is just copy, then intersection is everything. someList logic: outlist ++ [first], rest(rest) → takes every alternate element? Yes 1, 3, 5...? I may need to re-read to be 100% sure for Theory, but for extraction this is fine. I’ll stick to the extraction.)
