Answer 1

Check whether all lists have the same size.

Place the informations in a Matrix (List with List elements, for example) to get the number of lists and size of a list.

Create a new Matrix with the rotated size informations. (3x4 to 4x3)

Implement 2 For loops and place the elements into the new matrix.
