Move all zeros in a list to the end while maintaining the relative order of non-zero elements. Return the modified list. If the input is null, return null.
Examples:
Input: nums = [0, 1, 0, 3, 12]
Output: [1, 3, 12, 0, 0]
Explanation: All zeros moved to end, non-zeros maintain order
Input: nums = [1, 2, 3]
Output: [1, 2, 3]
Explanation: No zeros to move
Input: nums = [0, 0, 0]
Output: [0, 0, 0]
