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.

Solution in PHP7 (7.0.15) (judge verdict: Wrong Answer)

<?php
fscanf(STDIN,"%d%d",$h,$w);
for($i=0;$i<$h;$i++){
  $c_li[]=str_split(trim(fgets(STDIN)));
}
$re_li = array();
//print_r($c_li);
$ii=0;
for($t=0;$t<2;$t++){
  for($i=0;$i<$h;$i++){
    $index = (int)(($i+1)/2);
    for($j=0;$j<$w;$j++){
      echo $index." ".$j."\n";
      $re_li[$i][$j]=$c_li[$index][$j];
    }
  }
}
for($t=0;$t<2;$t++){
  for($i=0;$i<$h;$i++){
    for($j=0;$j<$w;$j++){
      echo $re_li[$i][$j];
    }
    echo "\n";
  }
}
