Stack quiz problem
You also need to check at the end after the loop terminates that if the stack is empty or not.
If the stack is not empty at the end then the expression must be unbalanced.
Example for ((())
At the end the stack will not be empty but according to the above code, it will print “balanced”
but we should also check if top of stack has ‘(’ then only we can pop na otherwise its not balanced but in question thats also not written.
kbut we should also check if top of stack has ‘(’ then only we can pop na otherwise its not balanced but in question thats also not written.
Just dry run the code with that option, you will get it.
