Book Price Search

You manage a bookstore's inventory system that returns the price of a book from a sorted list of prices. Given a list of book prices and a target price, design a function that finds the index of the target price or the next higher price. Input format: - The first line contains an integer N, the number of book prices. - The second line contains N integers of book prices in ascending order. - The third line contains an integer P, the target price. Output format: - Output the index of the target price if found, or the index of the next higher price if not found, or -1 if there is no higher price. Example: Input: 4 100 200 300 400 250 Output: 2
