Heap’s algorithm, i am utterly lost.
Hey there folks, So i've been doing the Advanced Algorithms challenges on FreeCodeCamp and i got to the "No repeats please" challenge.
I am utterly lost, i have no idea where to start, i know what permutations are (i think) but i have no idea how to generate them. I don't even know where to start, and I can't understand Heap's algorithm.
