Mock interview: DSA round (45 min, 2 problems)

Time-boxed mock — write code, talk through complexity, debrief.

DSA · NeetCode Binary Search

    Interview questions to prep

    1. State your loop invariant precisely — what must be true on every iteration?
    2. Why does the loop terminate, and how do you avoid infinite loops on the search-space update?
    3. Walk through edge cases: empty array, target smaller than min, target larger than max, duplicates.
