			//?????? H???????????????
			int H = sc.nextInt();
			//?????? W???????????????
			int W = sc.nextInt();
			//W??¨H???????????????0?????´?????????
			if(H == 0 && W == 0){
				break;
			}
			//??¨???
			System.out.println();
			//??????????????¨???
			for(int i = 1;i <= H; i++){
				System.out.print("???");
				//??????????????¨???
				for(int j = 1; j < W; j++){
					System.out.print("???");
