解题思路:

注意事项:

参考代码:

n=int(input())
dic1={}
dic2={}
for i in range(n):
        s=input().split()
        dic1[s[0]]=s[2]
        dic2[s[1]]=s[2]
m=int(input())
def print_(c,d):
        if c!=d:
                print("Y")
        else:
                print("N")
                
for i in range(m):
        a,b=input().split()
        if a.isdigit() and b.isdigit():
                print_(dic2[a],dic2[b])
        
        if not a.isdigit() and not b.isdigit():
                
                print_(dic1[a],dic1[b])
        if a.isdigit() and not b.isdigit():
                print_(dic2[a],dic1[b])
        if not a.isdigit() and b.isdigit():
               print_(dic1[a],dic2[b])
