Write a `2xx2` matrix which is both symmetric and skew-symmetric.

Explanation

As we know for a symmetric matrix `A^T=A`

And for a skew -symmetric matrix `A^T=-A`

Hence, if a matrix is both symmetric and skew-symmetric, then

`A=−A`

`2A=O`

`A=O`

Therefore, a 2×2 matrix which is both symmetric and skew-symmetric is null matrix i.e

`[(0,0),(0,0)]`
