2110. Number of Smooth Descent Periods of a Stock - LeetCode Solution

class Solution:
    def getDescentPeriods(self, prices: List[int]) -> int:
        count = len(prices)
        temp = 0
        for i in range(len(prices)-1):
            if prices[i] == prices[i+1] + 1:
                temp+=1
            else:
                temp += 1

                count+= (temp*(temp-1))//2
                temp = 0
        if temp:
            temp+=1
            count+= (temp*(temp - 1))//2
        return count
