題目描述

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.

輸入格式

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.

輸出格式

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.
