ASCI Mission Breakdown • Simple as Hell
"Master Sort a Linked List of 0's 1's and 2's: Take `nums` (number[]), execute an optimal medium problems of ll strategy, and return number[] with clean edge-case handling."
Real-World Metaphor:
Think of Sort a Linked List of 0's 1's and 2's as an everyday real-world challenge: you receive input data, inspect its elements in sequence without making unnecessary duplicate passes, and transform the collection to reach the exact target without wasting computer memory.

1. Initialize State for Sort a Linked List of 0's 1's and 2's
Load inputs and initialize algorithmic registers.
How to Think About This (Mental Model)
Unpack the problem parameters (`nums` (number[])) and clarify what is given vs what must be returned.
Identify the optimal data structure or pattern (e.g. pointers, hash map, or stack) to avoid redundant recalculations.
Walk through state transitions, handle edge cases (empty collections, single items, negative numbers), and return the verified result.
Given an array of integers `nums`, sort the array in ascending order using the **Sort a Linked List of 0's 1's and 2's** technique.
Return the sorted array.
Examples
Example 1
Input: nums = [5,2,3,1]
Output: [1,2,3,5]
Example 2
Input: nums = [5,1,1,2,0,0]
Output: [0,0,1,1,2,5]
Constraints
1 <= nums.length <= 5 * 10^4
-5 * 10^4 <= nums[i] <= 5 * 10^4
