Minor feedback regarding this puzzle. One of the test cases should probably be incorrect nesting, for example ‘{(})’. Currently there is no test case, even after submit to check this situation, making the puzzle easier that it should be.

Thank you.

Yeah, I was also surprised when my algorithm, which uses tree separate stacks, passed all test cases.


Still not fixed and invalid solutions continue to appear.

Usually these community puzzles can be edited by users with a sufficient level.
This one (as one of the oldest) is different, only the GC staff can edit it.

Unrelated: I just encountered a bug at the puzzle overview.
