Thank god I see the pattern on this question, otherwise I would have never done it lol

I think the better question to have is about whether the instructions given are consistent throughout the whole input, or whether it can change based on the order of the instructions, or what else. I am still confused and have given up on trying to solve this though lol

I genuinely have no idea what's going on with the instructions. There are so many inconsistencies with what's different between r and l, and r and R. I have been operating on the premise that one's supposed to be "walking but not turning" and one's "just walking", but it doesn't fit. At least, r and l isn't the same thing, and so is R and L.
