Solution in Python (3.8.2) (judge verdict: Accepted)

import sys

input=sys.stdin.buffer.readline


#sys.setrecursionlimit(10**9)
#from functools import lru_cache

def RD(): return sys.stdin.read()


def II(): return int(input())


def MI(): return map(int,input().split())


def MF(): return map(float,input().split())


def LI(): return list(map(int,input().split()))


def LF(): return list(map(float,input().split()))


def TI(): return tuple(map(int,input().split()))


# rstrip().decode('utf-8')


def main():
	print(1-II())
	

	

if __name__=="__main__":
	main()
