Hello @sktg99

In this question, you need to answer the number of different combinations of string a & b that can be used to make a + s + b balanced under the constraint that the length of a + s + b should be n.

The statement “At any index, number of opening brackets should be greater than closing brackets” should be “At any index, number of opening brackets should be greater or equal to number of closing brackets”

If you still face any problem, leave a reply and I will get back to you.
