矩阵求和挑战

下面的算法用于将“下矩阵”转换为“后矩阵”。给定“后矩阵”，找到“前矩阵”。

该算法针对每个 after(x,y) 运行以确定它们的值。给定之后，找到之前的原始值

例子

之后 = [[2,5],[7,17]]

从之前计算之后的值

after[0][0] = before[0][0] = 2

after[0][1] = before[0][0] + before[0][1] = 2 + 3 = 5

after[1][0] = before[0][0] + before[1][0] = 2 + 5 = 7

after[1][1] = before[0][0] + before[0][1] + before[1][0] + before[1][1] = 2 + 3 + 5 + 7 =  17

完成函数 find before matrix 具有以下参数 after[n][m]: 一个 nxm 整数数组

返回： int[n][m] 表示前矩阵的 nxm 整数数组

约束

再输入一个样本
