  • Cheapest Shirt Color Sequence With No Color Repeated on Consecutive DaysMedium

    Buy one blue, green or red shirt on each of n days without buying the same color on consecutive days, and return the color sequence with the lowest total cost. The task asks for the actual sequence rather than only the cost, testing optimization over sequences and reconstruction of the unique optimal choice.

  • Fewest Stones Left After Merging Equal-Level PairsMedium

    Each stone has an integer level, and two stones of the same level can be merged into one stone of the next level, with merged stones able to merge again. Return the fewest stones that can remain after any sequence of merges, a problem that tests counting by level, cascading merges, and efficient handling of large inputs.

  • Smallest Larger Integer That Uses None of the Digits of nMedium

    Given a positive integer below 2^31, find the smallest integer strictly greater than it that uses none of its decimal digits, or return -1 when no such integer exists. The problem tests reasoning about allowed digit sets, leading zeros, answers longer than the input, and results that exceed the 32-bit range.

  • Three-Question OA With a Surprise 2-Minute AI Follow-upElevenlabs · Software Engineer · Online Assessment · Sep 2026

    Fresh out of the oven. 3 questions, increasing in difficulty I guess, with time limits of 25 minutes, 30 minutes and 45 minutes respectively. Question 1: Next Number The next_number function should return the smallest integer which is superior to n and whose digits are all different from all of n's digits. For example, next_number(654321) return 700000. If no such integer exists, then the functio…
