How to transpose a matrix without using t() function in R?

The objective of this question is to give practice with writing functions involving matrices. For any matrix A, the transpose of A, denoted AT (or sometimes A0), is the matrix whose rows are the columns of A and whose columns are the rows of A.

The t() function returns the transpose of an input matrix.

Call a function called my_t() that returns the transpose of a matrix without the t() function. Account for vector or matrix input. The output of my_t(x) and t(x) should be identical for any vector or matrix x.
