I was registering for ICPC and I realised I couldn’t leave the last name field blank, nor can i put characters other than alphabets. I don’t have any last name in any official document. What to do?
I realise its late and you may have already completed your registration.
The best option however is to ask the regional directors directly via email. (Since they are the most experienced officials and in charge of issuing certificates etc.)
Also; if you’ve already registered, let us know how did you solved this problem.
All the best for ACM ICPC
