Solve this problem using C++. Think hard and think...

I'm looking into DSU1 and DSU2 merge operations, focusing on how rev_index deletions impact performance. The complexity might reach O(n log n), so for large n, like 100k, operations might edge up to 1.7 million. This could be manageable with C++, but storing rev_index as vectors could introduce a linear deletion time for certain cases.
