Note: This one is a little more difficult. I suggest attempting this one (https://www.sysnative.com/forums/programming/6760-addition-ppc-challenge.html) before trying this challenge here.
Code:
5.231.58.182:1337
PPC comes from professional programming and coding.
Solve 100 Sudoku games and you will get the flag.
Just like the last challenge, you'll need to know about sockets to solve this one. This one is more difficult though because you will need to solve sudoku's fast, and 100 of them, ranging in difficulty. Because you'll get disconnected from the server if you wait too long, you'll have to actually implement/write a bit of code that can solve sudoku puzzles!
Good luck :thumbsup2:. This one I solved as well, so I'm sharing it here too.
*You can compare the flag you found when you solved this challenge, with this hash of the correct flag...
