题目大意 给你接下来每一天的气温,求出对于每一天的气温,下一次出现比它高气温的日期距现在要等多少天 解题思路 利用单调栈,维护一个单调递减的栈 将每一天的下标i入栈,维护一个温度递减的下标 若下一个温度p,比栈顶元素对应的温度p'要高,就出栈,且p就是p'的最近的“高温” 代码实现 from collections import deque class Solution: def dailyTemperatures(self, temperatures): ans = [0]*len(tempe…

题目标签:HashMap 题目给了我们一组温度,让我们找出 对于每一天,要等多少天,气温会变暖.返回一组等待的天数. 可以从最后一天的温度遍历起,从末端遍历到开头,对于每一天的温度,把它在T里面的index存入 temp[101] 保存.然后对于每一天的温度,从温度+1 到100 全部遍历后,找出变暖温度里离当天最近的那一天.存入answer.具体看code. Java Solution: Runtime: 8 ms, faster than 91.33% Memory Usage: 42.7…
