和为S的连续正数序列

双指针滑动法

class Solution:
    def FindContinuousSequence(self,tsum):
        # write code here
        if tsum < 3:
            return []
        res = []
        low = 1
        high = 2
        while low < high:
            sum = (low + high) * (high - low + 1) / 2
            if sum == tsum:
                res.append(range(low,high+1))
                low += 1
            elif sum < tsum:
                high += 1
            else:
                low += 1
        return res
