Coding Problems

Question 1: Ticket Management System

Q1: Design a ticket management system with priority queues.

Solution (Java):

class TicketManager {
    PriorityQueue<Ticket> tickets = new PriorityQueue<>(
        (a, b) -> {
            if (a.priority != b.priority) {
                return Integer.compare(b.priority, a.priority);
            }
            return Long.compare(a.createdAt, b.createdAt);
        }
    );

    public void addTicket(Ticket ticket) {
        tickets.offer(ticket);
    }

    public Ticket getNextTicket() {
        return tickets.poll();
    }

    public void updatePriority(String ticketId, int newPriority) {
        List<Ticket> temp = new ArrayList<>();
        while (!tickets.isEmpty()) {
            Ticket t = tickets.poll();
            if (t.id.equals(ticketId)) {
                t.priority = newPriority;
            }
            temp.add(t);
        }
        tickets.addAll(temp);
    }
}

Time Complexity: O(n log n) for priority update
