Customer Support Tickets

You are developing a customer support ticketing system where each ticket has a type and a priority. High-priority tickets (lower number) must be addressed first, and within the same priority, the order of arrival matters. Your task is to implement a system that processes the tickets based on their priority. The input consists of the number of tickets followed by ticket descriptions in the format '<type> <priority>'. Output the types of tickets in the order they will be addressed. Example Input: 5 technical 1 billing 2 technical 1 sales 3 billing 1 Example Output: technical thecnical billing billing sales
