1. Minimum Amount Alex has a list of items to purchase at a market. The owner offers to discount each item after the first one by the lowest marked price among the prior items. No item's price can be discounted below 0, and the list of items may not be reordered. Calculate the payable amount. Example prices = [2, 5, 1, 4] Alex pays 2 for the first item since there are no previous items to compare to. The second item costs 5-2 = 3. The third item is free: max(1 - min(2, 5), 0) = max(-1, 0) = 0. The fourth item costs 4 -1 = 3. The total cost to purchase all items is 2+ 3 + 0 + 3 = 8. The first item is never discounted and the minimum cost of any item is 0. Function Description Complete the function calculateAmountin the editor below. The function must return Alex's total cost to purchase all the items. calculateAmount has the following parameter(s): int prices[n]: the original prices of each of the items selected Returns: int: the total cost to purchase the items after any discounts are applied
