Brainfuck program to generate next binary number
| - initial mark (FF) | |
| read input 49 = 1 and 48 = 0 (q0) | |
| >>,[>,<-------- -------- -------- -------- -------- -------- >] | |
| - final mark (FF) | |
| <[-<] change ones for zeros until a zero is found (q1) | |
| + change zero for one (q1 to q2) | |
| < ignore all characters until FF is found (q2) | |
| + increase by one (ensures that the data pointer moves until FF is found) | |
| [ if the byte at the data pointer is zero then FF was found | |
| - it wasn't zero decrease it | |
| < move left to check next bit | |
| + increase by one as before | |
| ] begin printing | |
| >-[>-]+ ensure that no leading 0s are printed | |
| + increase by one to ensure that the byte at the data pointer is not FF | |
| [ | |
| add 47 (to print the character as either 0 or 1) | |
| ++++++++ ++++++++ ++++++++ ++++++++ ++++++++ +++++++ | |
| . print character | |
| > go to next character | |
| + add 1 as before | |
