Can anyone kindly check and fix the test suite. It appears that the function name 'balance' already exists on Cody. Thanks.

Error using balance:
First argument must be single or double.

This problem should either be corrected or removed from the String II series as the function name 'balance' already exists on Cody server. Hence, the String II badge can no longer be earned. Really discouraging...

Kindly correct the test suite.

I think this dude's "anyone" probably means you: @goc3 :)

J. S. Kowontan on 17 Jul 2018

@Bainhome, Thanks for the clarity. :)

goc3 on 23 Jul 2018

Thanks for the tag, @bainhome. This problem has been fixed so that it is now solvable again.

This problem needs more test cases. For instance, ')(' is not balanced, and it would break a lot of "solutions".
