If you see someone in front of 200 meters off the wallet, how would you do?
Users questions: This is an IT job interview questions ...
Experts answer: ordinary IT person's eyes is not so well, some 200 meters away could see the purse? You can determine his or toilet paper out of a wallet or anything else? Besides he has to really round out not in my wallet also told him that he will remind the people around . So I think this question a bit unrealistic.
