难度中等给定一个整数数组 temperatures
,表示每天的温度,返回一个数组 answer
,其中 answer[i]
是指对于第 i
天,下一个更高温度出现在几天后。如果气温在这之后都不会升高,请在该位置用 0
来代替。
示例 1:
输入: temperatures
= [73,74,75,71,69,72,76,73]
输出: [1,1,4,2,1,1,0,0]
示例 2:
输入: temperatures = [30,40,50,60] 输出: [1,1,1,0]
示例 3:
输入: temperatures = [30,60,90] 输出: [1,1,0]
提示:
1 <= temperatures.length <= 105
30 <= temperatures[i] <= 100
class Solution: def dailyTemperatures(self, temperatures: List[int]) -> List[int]: stack = [] n = len(temperatures) res = [0]*n for i in range(n): cur = temperatures[i] while stack and cur > temperatures[stack[-1]]: top = stack.pop() res[top] = i-top stack.append(i) return res
