Using the rear of the linked list as the top of the stack is the most efficient way to manage the stack. A. True B. False

Analysis

Using the rear of a linked list as the top of the stack can be considered an efficient way to manage the stack structure. Here's a breakdown of this reasoning:

1. Linked List Structure: A linked list consists of nodes, where each node contains data and a pointer to the next node. If you consider the rear (or tail) of the linked list as the top of the stack, you can utilize efficient insertion and removal operations.

2. Operations Efficiency: In a linked list:

   • Push Operation: Adding an item (push) to the rear of the linked list can be done in constant time $O(1)$ since you can directly append the new node at the end.
   • Pop Operation: Removing an item (pop) from the rear can also be performed in $O(1)$ time if you maintain a pointer to the previous node of the tail.

3. Comparison with Front: If the linked list is managed with the front as the top of the stack, the push operation would still be efficient, but the pop operation would require traversing to the last node each time (which is $O(n)$), making it less efficient.

Conclusion

Thus, it is efficient to manage a stack using the rear of a linked list as the top.
