Description
You are given a 7-segment display connected to inputs that you control, numbered from Bit 0 to Bit 8 as shown in the image 7segments.png.
You need to provide the 8 sequences of 9 bits providing the sequential output shown in the image fcsc2022.png.
Note: the flag is FCSC{XXX}, where XXX is the sequence of bits found (so a sequence of characters ‘0’ and ‘1’).
Example: the flag for the sequence 789 would be FCSC{011100100111111111101101110}.
