My approach to this problem is not working
Ik this code fails for ((a+b)) , but i also know i am somewhat close to the answer, can you guide me further using my appoach and my code.
Approach unclear
Hi @nishchay-verma… firstly sry in delay… so what u can do is maintain a stack of char as u are doing. now if string has any character other than a closing bracket ‘)’ simply push it in ur stack. else what u do when u have a closing bracket u maintain a cnt variable to 0. now u start popping till u get a closing bracket. if cnt is still zero this means bracket was redundant and u break and print duplicate else u continue…
refer this code https://ide.codingblocks.com/s/587770
if u still face any difficulty msg back here.
ooh yess i got it…
