Given an array of integers representing the price of different laptops, and an integer representing your budget, return:

1. The second most expensive laptop if it is within your budget, or
2. The most expensive laptop that is within your budget, or
3. 0 if no laptops are within your budget.

• Duplicate prices should be ignored.
