Sort Array of 0s, 1s, and 2s (Dutch National Flag)

Given an array `nums` with `n` objects colored red, white, or blue represented by integers `0`, `1`, and `2` respectively, sort them in-place so that objects of the same color are adjacent, with the colors in the order 0, 1, and 2. ### Constraints - `n == nums.length` - `1 <= n <= 10^5` - `nums[i]` is either `0`, `1`, or `2`. ### Input Format A single line of space-separated integers containing only 0, 1, and 2. ### Output Format Print space-separated integers representing the sorted array.
