Given a list of integers, return a new list where each element at index i is the product of all elements in the original list except the one at index i. Do not use division. Return an empty list for null or empty input.
Examples:
Input: nums = (1, 2, 3, 4)
Output: (24, 12, 8, 6)
Explanation: Index 0 = 2*3*4=24, Index 1 = 1*3*4=12, Index 2 = 1*2*4=8, Index 3 = 1*2*3=6
Input: nums = (0, 1, 2, 3)
Output: (6, 0, 0, 0)
Explanation: Index 0 = 1*2*3=6, others include 0 so product is 0
Input: nums = (3, 5)
Output: (5, 3)
Explanation: Each element is the other element
Input: nums = (7)
Output: (1)
Explanation: No other elements, product is 1
Input: nums = null
Output: ()
Explanation: Null input returns empty list
