Boss, last wale case m, in the whileloop, when you are checking on the opening brackets anyways, so can't we just return true at the end when we get out of the while loop?

[@AKASHKUMAR-li7li]

can this be solved in one go for a begineer who has just started solving leetcode questions.... having basic knowledge of stack...?

[@shashwat_tiwari_st]

You can watch stack series parenthesis pattern and last 2 days leetcode challenge questions.
This question will become very easy because the pattern is more or less similar. Solving for the first time then yes, it will difficult to visualize a stack here.
