You are given an integer array nums containing only 0, 1, and 2. Sort the array in-place so that: - All 0s appear first - Followed by all 1s - Followed by all 2s You must: - Solve it in O(n) time complexity - Use O(1) extra space (in-place sorting) - Avoid using built-in sort functions Example - Input - nums = [2,0,0,0,1,1,1,2,2,1,0,2] - Output - [0,0,0,0,1,1,1,2,2,2,2,2] - Constraints 1 <= nums.length <= 10^5 nums[i] is either 0, 1, or 2 Follow-up Can you solve this problem in a single pass?
