코드

import sys
from collections import deque
input = sys.stdin.readline

if __name__ == "__main__":
    n = int(input())
    cards = [i for i in range(1, n+1)]
    result = []
    q = deque(cards)

    while q:
        if len(q) <= 1:
            result.append(*q)
            break

        result.append(q.popleft())
        q.rotate(-1)
    
    print(*result)

 

그리고 이렇게도 표현 가능하다.

import sys
from collections import deque
input = sys.stdin.readline

if __name__ == "__main__":
    n = int(input())
    q = deque(range(1, n+1))
    result = []

    while q:
        result.append(q.popleft())
        
        if q:
            q.append(q.popleft())
    
    print(*result)
