Gallery Queue Sort
In the rooftop gallery's preview, tablets log badge numbers as guests arrive. The log is a jumbled list, and the curator needs a routine to sort it from Smallest to Largest for the hospitality display. In Gallery Queue Sort, your job is to produce this orderly sequence without altering the original raw audit log.
The "secret sauce" is Stability and Integrity. You must keep every number that appeared, including duplicate badges for pairs and negative placeholders for elevator pauses. No values should be dropped or summarized—just rearranged into a clean, ascending order. If the list is empty, the routine should return an empty queue. This ensures that the hostess sees a calm, inviting invitation list that perfectly matches the physical badges being used. Mastering these sorting fundamentals is key to building professional data displays and event logistics tools for any high-end venue!
If sorting is part of the strategy, do it intentionally as a preprocessing step to simplify downstream logic such as merging, ordering, or comparison. After sorting, keep output semantics precise: preserve expected structure, avoid dropping valid entries, and ensure tied cases still follow deterministic order rules.
Examples
Negative placeholders and repeated badges stay visible in ascending order.
The guest queue now rises from the lowest badge to the highest while keeping both copies of 3.
A single badge remains unchanged because it already satisfies the order.
