Taotao is glad to see that lots of students have registered for today's algorithm competition. Thus he wants to pull a banner on the wall. But Taotao is so stupid that he doesn't even know how to enlarge words to fit the size of banner. So Taotao gives you a slogan template and asked you to enlarge them in k times.
输入解释
There are multiple test cases. For each test case, first line contains three numbers n, m, k (1<=n, m<=100,1<=k<=10). The next n lines each contain m visible characters.
输出解释
For each test case, you should output k*n lines each contain k*m visible characters to represent the expanded slogan.
