How to Create a Problem

If you are a real_admin or a (On Vijos)vijos_admin/(On Hydro)hydro_admin, you can create a problem online indivially.

If you are a normal member, you can first create your problem locally on your computer, then contact one of the admins,
then give the problem to the admin as a zip file, and the admin will upload the problem for you.
Don't forget that you should put your name on the problem.

Note that cheaters and forbiddens can’t create problems on AOCode.

Images

In many cases, we need to insert an image in problems or contests. Then, you need to use a picture bed.

Here we warn you:

• Don’t use the picture bed of Luogu. Vijos can’t use Luogu's picture bed. Use others instead, like the ImgTP Picture Bed.
