Dedupe Titles in Viewport

The Netflix home page has a list of shelves, each containing a number of titles. We want to deduplicate these titles in the viewport (each shelf can display a maximum of X unique titles). Vertical scrolling can be ignored. Implement a function to deduplicate these titles: def dedupe_v5(titles: list[list[int]], x: int) -> list[list[int]]: This function should return a list where each element is a potentially deduplicated list. Parameters: titles: A list where each element is a list of titles on a shelf. Titles are represented by integers. x: Maximum number of unique titles that can be displayed in the viewport per shelf. Example: >>> dedupe_v5([[1, 2, 2, 3, 4], [1, 2, 5, 6, 4]], 3) [[1, 2, 3, 4], [5, 6, 4]] >>> dedupe_v5([[5, 5, 1, 2], [1, 1, 1, 2, 3]], 1) [[5], [1, 2, 3]] Constraints: 1 <= x <= 100 1 <= titles[i].length <= 100 1 <= titles[i][j] <= 1000 Example Input [[1, 2, 2, 3, 4], [1, 2, 5, 6, 4]] 3 Output [[1, 2, 3, 4], [5, 6, 4]]
