This simply uses the ASCII table.

We can see that the problem gives us a series of bits 0.1 and every 7 bits separated by `!`

So the idea is that we're going to convert each of these 7 bits to decimal, and use the ascii table to convert it to characters, and then use the "EHCON" search command and we'll get the flag.

`Flag: EHACON{4ll_7h3_b35T}`
