Problem 1303. Is the paranthesis sequence balanced ?

Solve Later

Quantum mechanics and computer science are interested in bra-kets. Today however you, the player, will have to write a function to find if the given parenthesis expression is balanced.

e.g.

>> balance('(()()())')
   1

>> balance('(()()())(') 
   0

>> balance('(())))()())')
   0

>> balance('(((()))((())))')
   1

Hint: consider using a stack. Review your basic data structures for ideas.

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.
