Please solve the programming task below using a self-contained code snippet in a markdown code block.

Given an array of integers temperatures represents the daily temperatures, return an array answer such that answer[i] is the number of days you have to wait after the ith day to get a warmer temperature. If there is no future day for which this is possible, keep answer[i] == 0 instead.
 
Please complete the following python code precisely:
```python
class Solution:
    def dailyTemperatures(self, temperatures: List[int]) -> List[int]:
```
