Write a function transpose(matrix) that returns the transpose of the input matrix, which is represented as a list of lists. Reca
ll that the transpose of a matrix is obtained by swapping its rows with its columns. More concretely, the equality matrix[i][j] transpose(matrix)[j][i] should hold for all valid indices i and j. You may assume that the input matrix is well-formed, i.e., that each row is of equal length. You may further assume that the input matrix is non-empty. Your function should not modify the input. transpose([[1, 2, 3]]) [[1], [2], [3]] transpose([[1, 2], [3, 4], [5, 6]]) [[1, 3, 5], [2, 4, 6]]
