今天看到个帖子要打印杨辉三角和菱形，哥一时兴起，准备大展身手，结果悲剧的发现---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
哥不会了。。。。。

憋了半天憋出了一段破代码



	 //楊輝三角

	 public static void main(String[] args) {

	 int m = 10;

	 int n = 2 * m + 1;

	

	 long[][] arr = new long[m][n];

	

	 arr[0][m] = 1;

	

	 for (int i = 1; i < m; i++) {

	 for (int j = 1; j < n - 1; j++) {

	 arr[i][j] = arr[i - 1][j - 1] + arr[i - 1][j + 1];

	 }

	 }

	

	 for (int i = 0; i < m; i++) {

	 for (int j = 0; j < n; j++) {

	 System.out.printf("%3s", arr[i][j] == 0 ? "  " : arr[i][j]);

	 }

	 System.out.println();

	 }

	 }



	// 對稱菱形

	public static void main(String[] args) {

		int m = 20;



		int rows = 2 * m + 1;

		int cols = 2 * m + 1;



		String[][] s = new String[rows][cols];



		for (int i = 0; i <= m; i++) {

			for (int j = 0; j <= i; j++) {

				s[i][m - j] = "*";

				s[i][m + j] = "*";

			}

		}



		for (int i = m + 1; i < rows; i++) {

			for (int j = i - m; j <= m; j++) {

				s[i][j] = "*";

				s[i][rows - j - 1] = "*";

			}

		}



		for (int i = 0; i < rows; i++) {

			for (int j = 0; j < cols; j++) {

				System.out.printf("%2s", s[i][j] == null ? " " : s[i][j]);

			}

			System.out.println();

		}

	}
