Question

A linked list of Strings named list has been declared and initialized.

Assume that the following code is run on list:
(""A""); list.addFirst(""B""); list.addLast(""C""); (0); list.addFirst(""D""); (""C""); list.addFirst(""E""); list.addLast(""F""); (3); list.addFirst(""G""); list.addFirst(""H""); (""G""); list.addLast(""I""); list.addLast(""J"");
What does list now contain?

Answer 1

After applying a series of add and remove operations, the linked list 'list' contains the elements in the following order: H, E, D, A, I, J.

Step-by-step explanation:

The question involves operations on a linked list containing strings. The linked list list is manipulated through a series of add and remove operations. Here's how list changes step by step:

1. Add "A".
2. Add "B" at the beginning. List now contains: B - A
3. Add "C" at the end. List now contains: B - A - C
4. Remove the element at index 0 ("B"). List now contains: A - C
5. Add "D" at the beginning. List now contains: D - A - C
6. Remove the element "C". List now contains: D - A
7. Add "E" at the beginning. List now contains: E - D - A
8. Add "F" at the end. List now contains: E - D - A - F
9. Remove the element at index 3 ("F"). List now contains: E - D - A
10. Add "G" at the beginning. List now contains: G - E - D - A
11. Add "H" at the beginning. List now contains: H - G- E - D - A
12. Remove the element "G". List now contains: H - E - D - A
13. Add "I" at the end. List now contains: H - E - D - A - I
14. Add "J" at the end. Final content of the list: H - E - D - A - I - J
