c++ - 怎样将一个矩阵分成均等的四份？求教算法思路。

Question

如题。
会有奇数行奇数列的情况，想请教下算法思路。

Answer 1

How is it considered equal? If the total number of matrix elements is not divisible by 4, then they cannot be equal, so this question is unreasonable

Answer 2

Is there any mistake? Are you sure that a matrix with odd rows and columns can be divided equally? ?
