Nano Snakeskin

u/bandaloo

this is great! i'll definitely be using this substitute for a doubly-nested for loop
u/DataMeta

agreed, cool trick! even more succinct than the nested hack I've been using, and the perf increase from bitwise ops is welcome
u/tomxor

Yes, I've used this so much, I guess it's just more obvious in this one. I've taken technique a step further in d/20707 converting yonatan's 3 loops into one. bitwise can be very powerful to manipulate the variables a loop traverses.
