public class Main {
	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		
		int T = Integer.parseInt(br.readLine());
		
		for(int i = 0; i < T; i++)
		{
			String str = br.readLine();
			System.out.print(str.substring(0, 1));
			System.out.print(str.substring(str.length() - 1, str.length()));
			System.out.println();
		}
