Useless Brackets: Vikas Sir

Given a an expression find whether there are useless brackets or not
example
(A(+)B) useless bracket around + sign

push the operators and operands until u get a closing bracket . on getting it pop the topmost element store it in a temp var pop once more(this time the opening bracket).push the saved one .
plzz tell me whether dis will work or not

How about converting to prefix.removing all brackets,
converting back??

i also think above answer will work is there any other better solution??
