LinkedIn Zip #414 Answer & Analysis

The early cluster is packed into the upper-left quadrant, so the path must leave 1 in a way that still preserves access to 2 and 3. The opening settles naturally into a short drop before turning onto 2.

After 2, the path has to return through 3 and 4 before committing to the long edge run. Once 4 is reached, the left border becomes the cleanest way to continue without trapping future cells.

The lower-left section is a long, forced run. After 5 and 6, the route must weave through 7 and 8, then keep going across the bottom row to avoid isolating the far-right side.

From the far right, the path must climb upward and then swing left across the top row. That move creates room for 10 through 15 in the center without trapping any cells.

The final section is forced by the need to use every remaining cell exactly once. The last move sequence drops through the center-right corridor and ends on the final number.
