def solution(chicken):
    answer = chicken // 10
    inventory = [chicken % 10, chicken // 10]
    while sum(inventory) >= 10:
        if inventory[0] >= 10:
            inventory[0] -= 10
            inventory[1] += 1
            answer += 1
        elif inventory[1] >= 10:
            inventory[1] -= 10
            inventory[0] += 1
            answer += 1
        elif sum(inventory) >= 10:
            inventory = [0, 1]
            answer += 1
    return answer


# Test Cases
print(solution(100))
print("="*50)
print(solution(1081))
print("="*50)

  못나게 풀었습니다. 나중에 다시 풀어야겠어요.

def solution(chicken):
    return int(chicken*0.11111111111)

  대단하네요.

def solution(chicken):
    answer = (max(chicken,1)-1)//9
    return answer

  이것도 좋습니다.
