[PTI] Chander Test 18
Here we go. Even after having gone through every part of the puzzle for several times I never was sure (something wrong with my memory

@greykarel: that was fun to watch. But I'm pretty sure at least segments 1 & 3 can be done in fewer steps. I might make a video tomorrow of my solution. We can compare the number of button presses.
Here, for example, is the first section done in four buttons:

Yeah, I don't pretend to record the shortest way. And I realise there may be some different ways to solve the puzzle. As I said before, by the time I finished it the first time I had forgot how I did the initial part and I felt I did it different when I solved it again before recording.
Yeah, it took me longer to optimize the route than it did to find my first solution. Here is my route for the second pass through the hallway, done in three buttons:

And here is the third pass through, done in two buttons:
