Sort colors

CodingAlgorithms & data structuresMid–Senior~25 min

Given an array of 0s, 1s, and 2s, sort it in a single pass using constant extra space. Return the sorted array.

Implement
sort_colors(nums: list[int]) → list[int]
Examples
in[[2,0,2,1,1,0]]out[0,0,1,1,2,2]
What a strong answer looks like

State 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.
