leetcode讲解--739. Daily Temperatures

题目

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].

这道题挺简单的，往后找比当前温度大的就行了。

Java代码

class Solution {
    public int[] dailyTemperatures(int[] T) {
        int[] result = new int[T.length];
        for(int i=0;i<T.length;i++){
            int index = i+1;
            while(index<T.length && T[index]<=T[i]){
                index++;
            }
            if(index==T.length){
                result[i] = 0;
            }else{
                result[i] = index-i;
            }
        }
        return result;
    }
}
