I know that performing arithmetic on large integers in brainfuck, while perhaps quite tedious at times, is entirely possible.
However what I'm wondering about is what the generally acceptd best-practices are for taking in large integers (or even strings, I suppose) as input.
Most compilers/interpreters allow you to provide full strings at once as input (and then each character is read in individually with a
