Questions & Step-by-Step Solutions
Which of the following is true about linked lists compared to arrays?
Step 1: Understand what an array is. An array is a collection of items stored at contiguous memory locations.
Step 2: Understand what a linked list is. A linked list is a collection of items where each item points to the next one, allowing for non-contiguous memory storage.
Step 3: Learn about insertion in arrays. When you insert an item in an array, you may need to shift other items to make space, which takes time.
Step 4: Learn about insertion in linked lists. In a linked list, you can insert an item by simply changing pointers, which is faster and does not require shifting other items.
Step 5: Learn about deletion in arrays. When you delete an item from an array, you also need to shift the remaining items to fill the gap, which takes time.
Step 6: Learn about deletion in linked lists. In a linked list, you can delete an item by changing pointers, which is quicker and does not require shifting.
Step 7: Conclude that linked lists are more efficient for insertions and deletions compared to arrays because they do not require shifting elements.
