杨辉三角java代码，要求是等边三角形，不限制行数

public class YangHuiTriangle {
public static void main(String[] args) {
triangle(5);
}

public static int[][] triangle(int n) {
int[][] yh = new int[n][n];
for (int i = 0; i <= n-1; i++) {
for (int j = n; j >= 0; j--) {
System.out.print(" ");
if (i >= j) {
if (i == 0 || j == 0) {
yh[i][j] = 1;
System.out.print(yh[i][j]);
} else {
yh[i][j] = yh[i - 1][j - 1] + yh[i - 1][j];
System.out.print(yh[i][j]);
}
}
}
System.out.println();
}
return yh;
}
}
结果：
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
