    Merges multiple sorted lists into a sorted list that contains
    only distinct items from the source lists.
    Current implementation uses sorting, so it is not very efficient for
    very large lists.

    Example:
        - input:  [[0, 1, 2, 4, 5], [0, 1, 2, 3, 5]]
        - output: [0, 1, 2, 3, 4, 5]
