		// ?????°?????????
		int cnt1 = 0;
		int cnt2 = 0;

		while(true) {

			int H = sc.nextInt();
			int W = sc.nextInt();

			if(H == 0 && W == 0) {

				System.out.print("\n");
				break;

			} else {

				for(cnt1 = 0; cnt1 < H; cnt1++ ) {

					for(cnt2 = 0; cnt2 < W ; cnt2++ ) {
						System.out.print("#");
					}
				System.out.print("\n");

				}
