Sort by Distance from Zero

The space station lists nearby objects by how far they are — direction doesn't matter, minus signs are just directions. 🛰️

You get a list of nums. Sort them by distance from zero, closest first (ties keep original order), and print comma-separated.

Example:

Input: nums = [-7, 2, -3, 10] Output: 2,-3,-7,10

Distances from zero are 7, 2, 3, 10. Sorting by key=abs gives closest-first: 2 (dist 2), -3 (dist 3), -7 (dist 7), 10 (dist 10).
