@Hk199977 please save your code on cb.lk/ide and share link of your code.

@Hk199977

  • Line 35: What are you supposed to do with the return value of your function?
  • Line 30: Why are you returning “s.empty()”?
  • Line 24: Where is the default case of your switch?

But the same problem was on hackerrank.I used the same code for that.It worked there but not working on CB IDE

Can u please correct my mistake in the code.

@Hk199977,
I can but that would benefit absolutely no one, I have actually tried submitting the above code after making the changes I recommended and it works just fine.
Try debugging them given the exact locations of the bugs, and don’t pay much attention to results of other platforms, if there’s a WA, there’s a bug, just find it.
BTW one more heads up, You aren’t handling switch cases well, you are not using ‘break’ statement, despite the given cases being mutually exclusive.
