reads n people information (name, surname, Personal
Identification number (PIN)) from two different regions.
Then, your program will merge the two lists
and sort people information according to PINs

Finally, the program will show the
k th positioned
person's information from the sorted list.
Input specification

output. Each of the following n lines
will have space separated people information:
- Name: At most 12 chars string containing only English letters.
- Surname: At most 12 chars string containing only English letters.
- PIN: 9 digit integer number
After the first list, there will be an integer number (m)
and the following m lines will have people information
from the second region where 1 ≤ n ≤ 5,000;
1 ≤ m ≤ 5,000 and 1 ≤ k ≤ 10,000.
Output specification
