	public static void main(String[] args) throws IOException {
		
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));
		StringTokenizer st;
		int n = Integer.parseInt(br.readLine());
		int m;
		String str;
		
		for(int i=0;i<n;i++) {
			st = new StringTokenizer(br.readLine());
			m = Integer.parseInt(st.nextToken());	
			str = st.nextToken();
			
			for(int j=0;j<str.length();j++) {
				for(int k=0;k<m;k++)
					bw.write(str.charAt(j));
			}
			
			bw.write("\n");
		}
		
		bw.flush();
		bw.close();
		br.close();
