Brackets, extreme edition - additional test case



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.
