Problem

Given a list of integers (with duplicates) and a list of container-type names (each one of 'set', 'list', 'tuple'), build groups by distinct value ascending. Group g_i is the list of every occurrence of the i-th distinct value (so duplicates show up multiple times). Round-robin assign group g_i to containers[i % len(containers)]. For each group, return {'container': <container name>, 'values': <values from the group, deduplicated and sorted ascending if container is 'set', otherwise in original order>}. Return one dict per group, in group order.

Summary

Round-robin the values. Keep rotating.
