        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.

        Example 1:
        Input: temperatures = [73,74,75,71,69,72,76,73]
        Output: [1,1,4,2,1,1,0,0]

        Example 2:
        Input: temperatures = [30,40,50,60]
        Output: [1,1,1,0]

        Example 3:
        Input: temperatures = [30,60,90]
        Output: [1,1,0]

        Constraints:
        1 <= temperatures.length <= 105
        30 <= temperatures[i] <= 100
