Daily Temperature Trend
You are given an array of daily temperatures where each element represents the temperature of a specific day. Write a function that returns an array indicating how many days you will have to wait until a warmer temperature. If there is no future day for which this is possible, put 0 instead. For example, the input temperatures [73, 74, 75, 71, 69, 72, 76, 73] results in the output [1, 1, 4, 2, 1, 1, 0, 0].
Example:
Input:
8
73 74 75 71 69 72 76 73
Output:
1 1 4 2 1 1 0 0
