So this is an interview question, apparently by a senior manager. The obvious reply should be: What do you mean by faster? Do u mean writing this code is faster? Reading this code is faster? Compilation is faster OR may be you mean execution is faster? In case you meant execution then could you please mention the kind of computer on which the execution will happen? By the way it seems that both the code will run forever and ever, you can't figure out who won a race until the race ends and here it seems the race is going on forever.
