Hello Gevorg,

An example string: (4+1)*2 - I want to return true if the parentheses are found and false if there are none or there is a partial match ( e.g. (2+2+1 will return false because there is only one parenthese and hence the equation is incomplete).

Regards

Can someone tell me whether the following does what its supposed to (i.e. look for opening/closing brackets in a string):

I'm afraid it's not clear enough what you are trying to match here. Perhaps you could give us an example of a string which would match the expression?

Regards,
