soal

Can you figure out what is in the eax register at the end of the main function?
Put your answer in the picoCTF flag format: picoCTF{n} where n is the contents of the eax register in the decimal number base.
If the answer was 0x11 your flag would be picoCTF{17}.
Debug this.

hint

You could calculate eax yourself, or you could set a breakpoint for after the calculcation and inspect eax to let the program do the heavy-lifting for you.
