Newport Blake CTF 2023
Not Accepted [365 pts]
Challenge Description:
I can’t seem to pass this problem… can you help me? https://codeforces.com/contestInvitation/9cf6e56adf19ecb8e5dd7af8a9c5bf5610c8e46e
We’re given an odd Codeforces problem:
Simply submitting a Python program of
print(5)
Solves the problem and gives us the first part of our flag: nbctf{n1C3_
I tried to run ls to see if perhaps there were some hidden files in the system, but inadvertently got the next flag due to Wrong output format!
L_mY_V3rd1cTs}
A simpler program to get the above flag could be the following:
print(5)
print(5)
Eventually, I ended up trying to see if just printing 4, the actual answer to 2+2, would work. And to my surprise, it did!
y0U_90t_4l
Therefore, our flag is:
nbctf{n1C3_y0U_90t_4lL_mY_V3rd1cTs}
Sidenote: this challenge is a little bit guessy, but then again, this is the misc category
