Problem:
Score : 200 points

Problem Statement

There is an image with a height of H pixels and a width of W pixels. Each of the pixels is represented by either . or *. The character representing the pixel at the i-th row from the top and the j-th column from the left, is denoted by C_{i,j}.

Extend this image vertically so that its height is doubled. That is, print a image with a height of 2H pixels and a width of W pixels where the pixel at the i-th row and j-th column is equal to C_{(i+1)/2,j} (the result of division is rounded down).

Constraints

1≦H, W≦100

C_{i,j} is either . or *.

Input

The input is given from Standard Input in the following format:

H W
C_{1,1}...C_{1,W}
:
C_{H,1}...C_{H,W}

Output

Print the extended image.
