Given the 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 array where the `ith` element is the final price you will pay for the `ith` item of the shop considering the special discount.

Example 1:

    Input: prices = [8,4,6,2,3]
    Output: [4,2,4,2,3]
    Explanation:
    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.

Example 2:

    Input: prices = [1,2,3,4,5]
    Output: [1,2,3,4,5]
    Explanation: In this case, for all items, you will not receive any discount at all.

Example 3:

    Input: prices = [10,1,1,6]
    Output: [9,0,1,6]

Constraints:

- `1 <= prices.length <= 500`
- `1 <= prices[i] <= 10^3`
