#A contact list is a place where you can store a specific contact with other associated information such as 
#a phone number, email address, birthday, etc. 
#Write a program that first takes in word pairs that consist of a name 
#and a phone number (both strings), separated by a comma. 
#That list is followed by a name, and your program should output 
#the phone number associated with that name. Assume the search name is always in the list.

#Ex: If the input is:

#Joe,123-5432 Linda,983-4123 Frank,867-5309
#Frank
#the output is:

#867-5309

pairs = input().split()

contact = {}

for pair in pairs: 
    name, phone = pair.split(',')
    contact[name] = phone

    #Read the name to search for
    search_name = input()

    print(contact[search_name])
