这里可以用正则匹配这样的骚方法

s=input()
import re
pattern1 = re.compile(r"[^A-Z]+")
pattern2 = re.compile(r"([A-Z])\1")
pattern3 = re.compile(r"([A-Z])[A-Z]*([A-Z])[A-Z]*\1[A-Z]*\2")
if pattern1.search(s) or pattern2.search(s) or pattern3.search(s):
    print("Dislikes")
else:
    print("Likes")

s=input()
ls=len(s)
flag=True
def judge(s):
    ls=len(s)
    if ls<4: return False
    for i in range(ls-3):
        for k in range(i+2,ls-1):
            if s[i]==s[k]:
                for j in range(i+1,k):
                    for l in range(k+1,ls):
                        if  s[j]==s[l]:
                            return True 
    return False

        flag=False
        break
    if judge(s[i:]):
        flag=False
        break 
if flag: print('Likes')
