. 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).
.
or *
.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}
