→ I got pleasure in re- discovering the distances in multiple dimensions 
.
=> Thanks a lot and good luck for your next Puzzle

It should be explicitly stated that a point name may consist of more than one letter.
Nice puzzle, fun and simple! Pro tip for this sort of puzzle: there’s no need to ever actually take the square root of anything in this case. If you’re not asked to return the actual distance, the comparison is the same regardless of whether you compare 2 sums or the square roots of those 2 sums. I saw a lot of solutions using sqrt when the solution would likely return exactly the same result if it was removed!
