Question: Is it possible to solve the problem without relying on the additional constraints? In the problem Kilonova-1495, we are tasked with performing a series of operations on a sequence of integers, including insertions, deletions, re-additions, and queries but the problem can be solve using the aditional constraints:

1. No insert operations between a re-add operation and the previous delete operation.
2. The number of re-added elements cannot exceed the number of elements deleted in the last delete operation.
3. At least one delete operation must occur between two re-add operations.

Is there a way to solve this problem in the general case without relying on these constraints?

It would be great if anyone could share an alternative approach or even provide an implementation that works without these restrictions. Any insights or thoughts would be greatly appreciated!
