The problem of the last contest was:`(x–n)² = -n`

n is the reputation of the individual participant, to make copying of the result harder.

The solution is again quite simple, if you know how complex numbers work:`x-n = √(-n)`

↓`x-n = √(-1) * √n`

↓`x-n = i*√n`

↓`x = n + i*√n`

Despite this simple solution there only was one participant(@addax).

If this situation consists the contest might end rather soon :(

No need for the random picker here.

@addax you won. Congratulations!

The next contest will start tomorrow.

I think I will remove `i`

from the equation, so anyone who knows a little math will be able to solve it.
