This is my first successful run at part 1

duration = 35ms

Very simple method (as usual)

This is my first successful run at part 2

duration = 30ms

For me - today's puzzle was quite an easy one
It didn't take much to alter Part 1 to complete Part 2

It'll still be interesting to see the HOF solutions for it though

Another version for Part 2

Part2, slightly over-complicated as I expected actions vocabulary to be extended , 1000ms for 1000 route items

Edit:

Part2, ~36ms with improved lookup for 1000 items

Part 1

60ms

Part 2

11.7 seconds without warp block (very slow)
79ms with warp block !
