I wrote a solution to reveal cards in increasing order. If there is a better way for me to replace the stock by using deque library so I do not need to pop and insert value into index 0 in every loop and also keep the same Big O(N)?



ex: Input: [17,13,11,2,3,5,7], Output: [2,13,3,11,5,17,7]

pop 2: list turns into [3,11,5,17,7,13]

pop 3: list turns into [5,17,7,13,11]



class Solution:
def deckRevealedIncreasing(self, deck):
"""
:type deck: List[int]
:rtype: List[int]
"""
s = sorted(deck)
stock =
while s:
if stock:
tmp = stock.pop()
stock.insert(0, tmp)
stock.insert(0, s.pop())
return stock
