정의 링크->http://www.polymath.co.kr/mathfun/6350

위 정의에 따를 때, 어떤 자연수열과 그 순서수열의 순서수열은 항상 같은가?

이 문제 어떠셨나요?

글쎄요

어려워요

유한한 자연수열의 순서수열을 자동으로 생성하거나 비교해주는 프로그램을 만들었어요!

위 온라인 인터프리터에서 기본 코드를 지우고 아래 코드를 실행해주시면 됩니다.

def OrderSequence(se):
orse=[]
for i in range(1,len(se)+1):
  for j in range(0,len(se)):
   if i==se[j]: orse.append(j+1)
return orse
def comparator(s1,s2):
l=len(s1)
if l!=len(s2): return False
else:
  for i in range(0,l):
   if s1[i]!=s2[i]: return False
return True
while True:
se=[]
print("""To do: Input number
Make ordersquence: 1, Compare natural squence with ordersquence: 2, quit: else""")
order=input()
print("input length:")
n=int(input())
print("input sequence:")
for i in range(0,n): se.append(int(input()))
orse=OrderSequence(se)
if order=='1': print(orse)
elif order=='2':
  if comparator(se,orse): print("same")
  else: print("different")
else: break
