I did it, I completed it. But seriously FreeCodeCamp contributors, was that really necessary? It was torture for me. Absolute concentrated torture.
But i did get it. So that’s pretty cool. 
“no repeats please” left me afraid to look at the next challenge, but here I go, off to look at it. Peeking around the corner at it like a scared child looks down a dark hallway…
Not much is going to seem impossible for you to do now, huh?
At least you were able to implement Heap’s algorithm. From my research when I was doing that challenge, it’s more efficient than plain changes. However, I couldn’t wrap my head around how Heap’s works. 
Congrats on finishing the challenge!!!
@PortableStick - Lets hope I am now undefeatable!
@ZackWard - I hear you when you say Heap’s algorithm was tough, and recursion only made it worse…
Thanks for the motivation guys. I feel so close to front end cert i can taste is.
