Can you create an augmented version of the following code:
```python
class Solution:
    def finalPrices(self, prices: List[int]) -> List[int]:
        res = []
        for i in range(len(prices)):
            for j in range(i+1,len(prices)):
                if prices[j]<=prices[i]:
                    res.append(prices[i]-prices[j])
                    break
                if j==len(prices)-1:
                    res.append(prices[i])
        res.append(prices[-1])
        return res
``` Provide the entire answer in JSON format.
