我如何将这个帕斯卡三角形变成正方形?
import java.util.*;
public class PascalSquare {
public static void main(String[] args) {
int row = 7;
int[][] pascal = new int[row +1][];
pascal[1] = new int[1 + 2];
pascal[1][1] = 1;
for (int i = 2; i <= row; i++) {
pascal[i] = new int[i + 2];
for (int j = 1; j < pascal[i].length - 1; j++) {
pascal[i][j] = pascal[i-1][j-1] + pascal[i-1][j];
}
}
for (int i = 1; i <= row; i++) {
for (int j = 1; j < pascal[i].length - 1; j++) {
System.out.print(pascal[i][j] + " ");
}
System.out.println();
}
}
}
//我希望这是一个7 * 7的方格,它遵循与pascal三角形相同的原则(添加上面的数字)
