Advanced — transpose<T>

📖 Usage Example

transpose([[1, 2], [3, 4], [5, 6]])   // → [[1, 3, 5], [2, 4, 6]]

transpose flips a matrix over its diagonal, converting rows to columns and vice versa.

Advanced: Matrix Transpose

Challenge: Implement transpose<T>(matrix: T[][]): T[][] rotating a 2D matrix 90° by swapping rows and columns.

transpose([[1,2,3],[4,5,6]])  // → [[1,4],[2,5],[3,6]]

💡 Hints (1)

• Map over the columns index of the first row, then map each row to that column.
