Kata

In this kata, you will need to make a function that can swap the rows of specified matrices. Example:

matrix = [[0, 1],
          [2, 3]]
          
swap(matrix, 0, 1, 0) # Matrix, 1st row to swap, 2nd row to swap, columns

should return

[[2, 1],
 [0, 3]]

because the 0th row is being swaped with the 1st row, but only in the 0th column.
