Goal
You want to easily encode and decode messages with a simple and personalized method. To do so, you will use a substitution method.
The principle is simple, you have a comparison table like this one:
A B
C D
and a message to encode written with the characters available in your table:
CBA
You are going to take each of the characters that compose the message and replace them by its position in the table:
C => 10 (row 1 column 0)
B => 01 (row 0 column 1)
A => 00 (row 0 column 0)
The message becomes: 100100
Input
Line 1: An integer rows for the number of rows of the table.
Next rows lines: A string for each row of the table. This string is composed of characters separated by one space.
Final line: The message to encode.
Output
Line 1: The encoded message.
Constraints
1 ≤ rows ≤ 10
All characters in the table are unique.
All characters in message can be found in the table.
