Problem Statement
You are given an integer array prices where prices[i] is the price of the ith item in a shop. There is a special discount for items in the shop. If you buy the ith item, then you will receive a discount equivalent to prices[j] where j is the minimum index such that j > i and prices[j] <= prices[i]. Otherwise, you will not receive any discount at all. Return an integer array answer where answer[i] is the final price you will pay for the ith item of the shop, considering the special discount.

Examples
prices = [8,4,6,2,3][4,2,4,2,3]For item 0 with price[0]=8 you will receive a discount equivalent to prices[1]=4, therefore, the final price you will pay is 8 - 4 = 4. For item 1 with price[1]=4 you will receive a discount equivalent to prices[3]=2, therefore, the final price you will pay is 4 - 2 = 2. For item 2 with price[2]=6 you will receive a discount equivalent to prices[3]=2, therefore, the final price you will pay is 6 - 2 = 4. For items 3 and 4 you will not receive any discount at all.
prices = [1,2,3,4,5][1,2,3,4,5]In this case, for all items, you will not receive any discount at all.
prices = [10,1,1,6][9,0,1,6]Constraints
