I've a fear of bracket sequence. Whenever I face one, It scares me. So, I'm gonna solve as many as possible. I was trying to make a list of problems which contains dealing with "Bracket Sequences". Here are some. Please suggest some if you've solved any. It'll be so kind if you comment the topic with the problem.

Happy Coding O_o.
