Question
A hiking game shows a trail of markers. Standing on marker i, your stamina lets you advance to any marker from i+1 up to i+jumps[i]; a value of 0 means you are stuck there. You start on the first marker. Return true if the last marker can be reached, false otherwise. A single-marker trail is trivially finished. For example, [2, 3, 1, 1, 4] is finishable but [3, 2, 1, 0, 4] is not.
can_finish_trail(jumps: list[int]) → bool[[2,3,1,1,4]]outtrue[[3,2,1,0,4]]outfalseState your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
