In this challenge, I had to determine which team is ahead by scores by inputting one or a zero based on the input. I quickly figured out the games were tennis since the words love, game, set which correspond to 0, 45, and 6 respectively. Giving the right answers to all the questions ends with a Thank you and a closed connection. This led me to realize that the flag is something that we already figured out, the input. The ones and zeros are binary.
