The next answer has to match the following strings:

PPCG
^P
^[P^]P
[^?][PG]$
(?<!\\..)(?!]).$
^[\w^]*$|!|]P|G]\$$
!|[^?]P(CG|G..)?$
[^])]\$|^\^?P|P.\].$
([.$?]|G\])\$$|^\^?P|\]P$
([P.$?]\$|[]^]P|G\]\$|CG)$
!|((G.|P|\.)\$|[^?]P|CG)$
^[(!P]|G..$|]..\||[^?]P$
^.{3,23}[.-~]..\$$|[^P?][PG]$
^..(.[!G)(3w^]|.{7}$|$)|\$\?
\.\)|P[.$?]|w\^|^[^|C\\]*$|^P
^..(.[!)3G^w]|$)|\^.{7}$|G\)

And fail on these strings:

[PPCG]
^[P\^]
[^\]]$
^\^?P
[^?][PG]$|<|PG
^[^\\|]*(\\\\)+[^\\|]*[^\]]$
^(.{,4}|.{9}|.{16,19}|.{5}P)$
^[^?]*[PG]$|[?$].*\$$
^[^[]P|]P|(G]|[.])\$$
\..$|!|\|G|^[\^P]P|P\^|G.\$$
...\^.P|^!|G]\$$|w|<!|^\^?P
([^\\}<]{3}|][^]]|^).?[$PG]$
^(..[^^].{4,22}\$|[^?]+\w)$|2
^(..[^^].{4,22}\$|[^?]+\w)$|~
^..(.[!()3G^w]|.{7}$|$)|G\\
[[?C(].[-!)|w]|^P|^[^C|\\]*$
[?[CP(].[-<)|w]|^P|^[^C|\\]*$
^..(.{7}$|.[3Gw!^)]|$)|G.?.?\)
