My friend is a delivery man and he asked me to help him find the shortest and most economical way for him to deliver all the goods.

What could I do to be a good friend xD?

I headed for a bath and suddenly realized that the coat hanger was nearly full, leaving just one spot available to hang my clothes. However, I had four items in my possession: a shirt, pants, a towel, and the mysterious fourth addition. Thankfully, thanks to my studies in CP, I was aware that there had to be a way to optimize this rather unfortunate situation.

Upon observation, I noticed that when I put on these clothes, I did so one by one. I started with the towel, then the mysterious item, then the regular pants, and finally, my shirt. At each step, I only needed to focus on managing the next item I was going to wear. So, I could simply hang my clothes in the reversed order they were put on. This observation reduced the total memory complexity from O(4) to O(1) :D.

Maybe you could negotiate to the path at most 1.5 times longer than the optimal instead
