Get Min Size
Reported by candidates from Amazon's online assessment. Pattern, common pitfall, and the honest play if you blank under the timer.
Amazon's "Get Min Size" showed up on assessments in August 2024, and it's a straightforward optimization problem disguised as a filtering task. You're likely looking at a collection of items or elements where you need to find the minimum size that meets some constraint. The trick is recognizing whether you're minimizing across a single dimension or balancing trade-offs. If you blank on the approach during the live OA, StealthCoder can read the exact problem and feed you the pattern in seconds, so you stay on track.
Pattern and pitfall
This problem typically involves either a binary search over answer space ("what's the smallest size that works?") or a greedy pass through sorted data. The common pitfall is trying to brute-force every possible size instead of recognizing that valid sizes form a monotonic range. Once you hit a size that satisfies the constraint, all larger sizes will too. That's your signal to binary search or use a two-pointer scan. Edge cases trip up half the candidates: empty input, single element, or ties at the boundary. During your live OA, if the problem statement is ambiguous, StealthCoder reads it and you can confirm the exact constraint before coding.
The honest play: practice the pattern, and have StealthCoder ready for the one you didn't see coming.
You can drill Get Min Size cold, or you can hedge it. StealthCoder runs invisibly during screen share and surfaces a working solution in under 2 seconds. The proctor sees the IDE. They don't see what's behind it. Built for the candidate who saw this exact problem leak two days before his OA and wondered if anyone had a play.

Get Min Size FAQ
Is this a binary search problem?+
Probably. If the question is "find the minimum X where Y becomes true," you're binary searching over possible X values. Check if the constraint is monotonic: once it's satisfied at size K, is it satisfied at all sizes > K? If yes, binary search. If no, you may need greedy or iteration.
What's the common mistake candidates make?+
Iterating from size 1 upward instead of binary searching. That works for small constraints but times out on large inputs. Also, misreading the constraint: make sure you know whether you're minimizing size, count, or cost, and under what conditions.
How do I prepare in 48 hours if I don't know the exact problem?+
Practice binary search on answer space (LeetCode 1011, 1283). Review two-pointer techniques for sorted arrays. Then, on OA day, read the problem statement twice before coding. Confirm the constraint with an example before submitting.
Does Amazon ask this pattern in other OA problems?+
Yes. Amazon loves optimization and constraint-satisfaction questions. "Get Min" variants appear often. The pattern is binary search or greedy. Mastering both will carry you across multiple Amazon OA problems.
Should I code a brute-force solution first?+
Only if you're stuck. Code clarity matters more than perfection, but a brute-force that times out loses points. If you blank on binary search during the live OA, a defensive brute-force is better than nothing. That's where StealthCoder helps: confirms the approach before you commit.
