杨辉三角形，找到上线的关系就简单了
{ int x=10; int num[][] = new int[x][x];
for(int m=0;m<x;m++) {
for (int n = 0; n <= m; n++) {
if (n == 0 || m == n) {
num[m][n] = 1;
} else
num[m][n] = num[m - 1][n - 1] + num[m - 1][n];
}
}
for(int i=0;i<x;i++) {
for (int l = i; l < x; l++) {
System.out.print(" ");
}
for (int j = x - i; j <= x; j++) {
System.out.print(num[i][x - j] + " ");
}
System.out.println();
}
