关于一些算法的例子

public class YanHui{
	public static void main(String args[]){
		int n = 10;
		int a[][] = new int[n][];
		for (int i = 0; i<n; ++i){
			if (i == 0){
				a[0] = new int[1];
				a[0][0] = 1;
				continue;
			}
			a[i] = new int[i+1];
			a[i][0] = 1; a[i][ a[i].length-1 ] = 1;
			for (int j = 1; j<a[i].length-1; ++j){
				a[i][j] = a[i-1][j-1] + a[i-1][j];
			}
		}

		for(int i = 0; i<a.length; ++i){
			for(int j = 0; j<a[i].length; ++j){
				System.out.print(a[i][j] + "\t");
			}
			System.out.println();
		}
	}
