What users must submit to solve a challenge
Challenges are the main form of content in CTFd. Most functionality in CTFd is centered around challenges and how users interact with them.
Primarily, when users interact with challenges, they can submit a flag (a.k.a. an answer) to the challenge and CTFd will reward the user with points.
