CGX#15: Still Binary (Encoding, Training, CGX)
CGX: Still Binary
Hello future Hackers,
Back in the Days, ASCII was only 7 bit.
The 8th bit, in particular the MSB was used as a check bit, the number of set bits modulo 2.
In challenges, you might encounter a stream of 0 and 1 using only 7 bits per byte.
A hint that this technique is used, might be when the number of bits is divisible by 7.
Your task now is to convert a stream to ASCII.
Greetings

- In old ASCII standard, only 128 different chars were defined
- The MSB (most significant bit) was a checkbit for error detection.
