Balanced Backpacks

Two hikers split the gear: heaviest item to hiker A, next to hiker B, next to A… taking turns down the sorted pile. 🎒

You get the gear weights. Deal them out that way and print A's total and B's total, separated by a space.

Example:

Input: weights = [8, 5, 3, 2] Output: 11 7

Sorted heaviest-first gives [8, 5, 3, 2]. Alternating deals 8 and 3 to hiker A (8+3=11) and 5 and 2 to hiker B (5+2=7).
