    85 - Maximal Rectangle.

    Hard

    Given a rows x cols binary matrix filled with 0's and 1's, find the largest rectangle containing only 1's and return its area.

    Example 1:

    Input: matrix = ["1","0","1","0","0","1","0","1","1","1","1","1","1","1","1","1","0","0","1","0"]

    Output: 6

    Explanation: The maximal rectangle is shown in the above picture.

    Example 2:

    Input: matrix = ["0"]

    Output: 0

    Example 3:

    Input: matrix = ["1"]

    Output: 1

    Constraints:

    • rows == matrix.length

    • cols == matrix[i].length

    • 1 <= row, cols <= 200

    • matrix[i][j] is '0' or '1'.
