Q: In that one song that I forgot the name of it supposedly scrolls through all the possible combinations of 6 letter like it's some base 26 counting system. The thing is that I inspected it came by frame and say that there was the word memory separating huge chunks of the combinations. Are those there to save memory or for some other reason?
A: to save memory and time in multiple ways. give it a try: try displaying all combinations of 6 letters in alphabetical order. try to do anything with it. try to save it in a file. try to send it to someone. try to depict its entirety on a screen in any way, in any reasonable amount of time and/or at a reasonable frame rate. i think you may be surprised at how astronomically large a quantity we're dealing with
