Part of the private RSA key is deleted. However, we can extract e,d,p,q which is sufficient to reconstruct the private key.

Some words are missing (literally) in the writeup after the point where they found public exponent.
Actually d, p and q were broken too, or did organisers updated the task during the ctf?
