Merge three ordered lists without repeats
Combine three nondecreasing integer lists into one nondecreasing list in which every distinct value appears once, then print it as a single space-separated line.
Practice focusRequirements - The input has exactly three lines. Each line starts with a count k followed by k nondecreasing integers. - The merged result must stay sorted and must contain each distinct value exactly once. - Values may be negative, zero, or positive. Duplicates can appear within one line and across lines. - Print the distinct values in one line separated by single spaces, with no leading or trailing space. - If all three lists are empty, return an empty string. - run case(case: dict) forwards case["stdin"] to solve .…
