My opinion is that you should make your best attempt on your own without input from others. As a coder and as interviewer it's often painfully obvious to me which candidates had 'help' to get to that point in the process. Landing the big job is not worth much if six months in you are let go or transferred because you didn't really meet the qualifications. (Not trying to say you don't deserve a job at google) I guess the best advice I could give is be yourself in how you solve it, employers often overlook minor skill deficiences in favor of character strengths. Good luck!
