Solution

When you delete an element from the middle of an array-based linear list, the remaining elements in the list will need to shift positions to fill the gap left by the deleted element. This process involves the following steps:

  1. Identify the Element: Locate the index of the element that is to be deleted.
  2. Shift Elements: Move all subsequent elements one position to the left. This means that for each element after the deleted element, its index will be decremented by one.
  3. Update Size (if applicable): If you are maintaining a size variable for the array, decrease the size by one to account for the removed element.

This operation can be computationally expensive, especially in large lists, because it may require moving many elements. The overall time complexity for deleting an element from the middle of an array-based list is O(n)O(n), where nn is the number of elements in the list, due to the shifting process.

So, the answer to the question is that the remaining elements will shift left to fill the space of the deleted element.
