Merge Two Sparse Sorted Lists Without Zeros

meta Merge Two Sparse Sorted Lists Given two lists of integers, list1 and list2, each containing a lot of zeros, but apart from the zeros, the elements are sorted. Merge these two lists into a single sorted list without zeros. Input: list1: A list of integers, e.g., [1, 0, 0, 0, 2, 0, 0, 0, 3, 0] list2: Another list of integers. Output: A merged sorted list of integers without zeros. Example: Input: [1, 0, 0, 0, 2, 0, 0, 3], [0, 2, 0, 0, 4, 5] Output: [1, 2, 2, 3, 4, 5] Example Input [1, 0, 0, 0, 2, 0, 0, 3], [0, 2, 0, 0, 4, 5]
