解题思路:

注意事项:

参考代码:

import math
def prime(n):
        if n<=1:
                return 0
        if n==2 or n==3 or n==5:
                return 1
        if n%2==0 or n%3==0 or n%5==0:
                return 0
        for i in range(7,int(math.sqrt(n)),2):
                if n%i==0:
                        return 0
        return 1
        
s=list(input())
s1=set(s)
l=[]
for i in s1:
        a=s.count(i)
        l.append(a)
m=max(l)-min(l)
if prime(m):
        print("Lucky Word")
        print(m)
else:
        print("No Answer")
        print('0')
