You and your friend have come up with a way to send messages back and forth.
Your friend can encode a message to you by writing down a positive integer and a symbol. You can decode that message by writing out that symbol times in a row on one line.
Given a message that your friend has encoded, decode it.
The first line of input contains , the number of lines in the message.
The next lines each contain one positive integer less than , followed by one space, followed by a (non-space) character.
The output should be lines long. Each line should contain the decoding of the corresponding line of the input. Specifically, if line of the input contained
x, then line of the output should contain just the character
x printed times.
