Make a function matrix(rows: int, cols: int) that returns a matrix of 'rows' rows and 'cols' columns where each value in the matrix is 0.Your function should have only one statement and must use list comprehensions.You'll earn only partial credit for solutions with more than one line.Be sure to include appropriate type hints.

e.g.

matrix(2, 3) == [[0, 0, 0], [0, 0, 0]] # 2 rows, each row has 3 columns
