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.

#include<stdio.h>

	int i,j;
	for(i=0; i<h; i++) {
		scanf("%s",str[i]);
//		gets(str[i]);
//		for(j=0; j>w; j++) {
////			cin>>str[i][j];
////			scanf("%c",&str[i][j]);

	}
	for(i=0; i<2*h; i++) {
		for(j=0; j<w; j++) {
			printf("%c",str[(i)/2][j]);

		printf("\n");
