## BJP5 Exercise 7.12: priceIsRight

Language/Type: Java arrays
Author: Roy McElmurry (on 2019/09/19)

Write a method `priceIsRight` that accepts an array of integers bids and an integer price as parameters. The method returns the element in the bids array that is closest in value to price without being larger than price. For example, if bids stores the elements `{200, 300, 250, 999, 40}`, then `priceIsRight(bids, 280)` should return 250, since 250 is the bid closest to 280 without going over 280. If all bids are larger than price, then your method should return -1.

The following table shows some calls to your method and their expected results:

 Arrays Returned Value `int[] a1 = {900, 885, 989, 1};` `priceIsRight(a1, 800)` returns 1 `int[] a2 = {200};` `priceIsRight(a2, 120)` returns -1 `int[] a3 = {500, 300, 241, 99, 501};` `priceIsRight(a3, 50)` returns -1

You may assume there is at least 1 element in the array, and you may assume that the price and the values in bids will all be greater than or equal to 1. Do not modify the contents of the array passed to your method as a parameter.
