문제

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 N and a symbol. You can decode that message by writing out that symbol N times in a row on one line.

Given a message that your friend has encoded, decode it.

입력

The first line of input contains L, the number of lines in the message.

The next L lines each contain one positive integer less than 80, followed by one space, followed by a (non-space) character.

출력

The output should be L lines long. Each line should contain the decoding of the corresponding line of the input. Specifically, if line i+1 of the input contained N x, then line i of the output should contain just the character x printed N times.
