为什么我在返回F（n-1，t）+ F（n，t-1）行时出错？

纳苏哈·达德（Nasuha Daud）

问题：

在数学上证明了以下2D递归关系控制这些值：

                      F(n,t) = F(n-1,t) + F(n,t-1)

现在，回答以下问题：

（b）通过使用递归方法，实现上述关系。

（c）使用（5,5），（10、10）和（14,14）测试您的方法

//主要方法

public static void main(String[] args) {
    // TODO code application logic here

    TwoDimension a = new TwoDimension();
    a.F(5, 5);
    a.F(10, 10);
    a.F(14, 14);
}

//班级

public static class TwoDimension {

    public TwoDimension() {

    }

    public long F(int n, int t) {

            if (t == 1) {
                return 1;
            } else {
                return F(n - 1, t) + F(n, t - 1);
            }


    }
}

这是输出

请帮助meeeee，如何维修退换货方法？
