Find Closest Meal Price

You run a meal delivery service and want to find the closest meal price to a desired budget. You have a list of meal prices and a budget given. You need to determine the price of the meal that is closest to the budget without going over. If no meal is available below the budget, return -1. Input: - The first line contains the integer N (1 ≤ N ≤ 10^5), the number of meal prices. - The second line contains N space-separated integers representing the meal prices. - The third line contains the integer B (0 ≤ B ≤ 10^9), the budget. Output: - A single integer representing the closest meal price to the budget without exceeding it, or -1 if all prices exceed the budget. Example: Input: 5 12 15 8 20 10 14 Output: 12
