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.
