Given a list of daily temperatures T, return a list such that, for each day in
the input, tells you how many days you would have to wait until a warmer temperature. If
there is no future day for which this is possible, put 0 instead.
For example, given the list of temperatures T = [73, 74, 75, 71, 69, 72, 76,
73], your output should be [1, 1, 4, 2, 1, 1, 0, 0].
Note:
The length of temperatures will be in the range [1, 30000].
Each temperature will be an integer in the range [30, 100].
