建议大家把情况一二三想清楚了，先写出版本一的代码，然后在其基础上在做精简！

Python：

classSolution:

defnextGreaterElement(self,nums1: List[int],nums2: List[int]) -> List[int]:

result= [-1]*len(nums1)

stack= [0]

for iinrange(1,len(nums2)):

if nums2[i]<=nums2[stack[-1]]:

stack.append(i)

else:

whilelen(stack)!=0and nums2[i]>nums2[stack[-1]]:

if nums2[stack[-1]]in nums1:

index= nums1.index(nums2[stack[-1]])

result[index]=nums2[i]

stack.pop()

stack.append(i)

return result

}

Python：

classSolution:

defdailyTemperatures(self,temperatures: List[int]) -> List[int]:

answer= [0]*len(temperatures)

stack= [0]

for iinrange(1,len(temperatures)):

if temperatures[i]<=temperatures[stack[-1]]:

stack.append(i)

else:

whilelen(stack)!=0and temperatures[i]>temperatures[stack[-1]]:

answer[stack[-1]]=i-stack[-1]

stack.pop()

stack.append(i)

return answer
