1. What to demonstrate in a technical interview?
✔️ Your ability to code.
❌ Soft skills
❌ Background & hobbies
2. Mathematical process for all binary permutations
✔️ Exponentiation
❌ Numeration
❌ Factorial
3. Which is quickest? O(n), O(2n), O(log n)
✔️ O(log(n))
❌ O(n)
❌ O(2n)
4. What is auxiliary space?
✔️ Additional space required for computations.
❌ Luxury space
❌ Unnecessary space
5. What does zero-based array mean?
✔️ Index count starts at 0.
❌ Cannot be changed
❌ Big-O applies to it
6. What does it infer that a list is an object?
✔️ It stores items and has in-built functions.
❌ Needs parameters
❌ Defined only by attributes
7. What does optimizing code mean?
✔️ Ensuring a program uses the least possible memory.
❌ Using as much network bandwidth
❌ Maximizing CPU time
8. Difference between DFS and BFS
✔️ DFS goes deep (top to bottom); BFS goes level by level.
❌ DFS is more detailed…
❌ BFS more thorough…
9. True statement about hash tables
✔️ Increases space usage to increase speed.
❌ Decreases speed…
❌ Decreases space…
10. Dynamic programming definition
✔️ False
❌ True
(DP is about solving subproblems + memoization, not dynamic data structures.)
