Sample Coding Quiz Questions
A flavour of what the AI generates — every question comes with an explanation that teaches, not just grades.
Q1. What is the time complexity of binary search on a sorted array?
- A.O(1)
- B.O(log n)
- C.O(n)
- D.O(n log n)
Explanation
Binary search halves the search space each step, giving O(log n). O(n) is linear search; O(n log n) is typical of comparison sorts.
Q2. In JavaScript, which of the following declares a block-scoped, reassignable variable?
- A.var x = 1
- B.let x = 1
- C.const x = 1
- D.x = 1
Explanation
`let` is block-scoped and reassignable. `var` is function-scoped; `const` is block-scoped but not reassignable; the bare assignment creates a global (in non-strict mode).
Q3. Which HTTP status code typically indicates a successful resource creation?
- A.200 OK
- B.201 Created
- C.204 No Content
- D.301 Moved Permanently
Explanation
201 Created indicates the request succeeded and a new resource was created. 200 is general success; 204 is success with no body; 301 is a permanent redirect.
Common Coding Mistakes
- ·Memorising syntax without understanding semantics — most bugs come from misunderstanding what code *does*, not from typos.
- ·Confusing time complexity and space complexity. They're measured separately.
- ·Treating shallow vs deep copy carelessly — a frequent source of mutation bugs.
- ·Skipping the README / docs for libraries. The docs are the source of truth, not Stack Overflow.
Study Tips for Coding
- ·Write the code on paper or a whiteboard before running it. Forces deeper engagement than IDE auto-completion.
- ·For each algorithm, learn one canonical implementation cold. Variations come from the canonical version.
- ·Solve 1–2 LeetCode easies daily for a month — fundamentals build through volume.
- ·Read other people's code. Open source repos with good test suites are the best teacher after the docs.
