Question
Which representation is more flexible for handling an indefinite number of values in a stack?*1 pointa. Array-based stackb. Linked list-based stackc. Both have the same flexibilityd. Neither can handle an indefinite number of values
Solution
To determine which representation is more flexible for handling an indefinite number of values in a stack, we need to compare the options provided: array-based stack and linked list-based stack.
- Array-based stack:
- An array-based stack uses a fixed-size array to store the elements of the stack.
- The size of the array determines the maximum number of elements that can be stored in the stack.
- If the number of elements exceeds the size of the array, the stack needs to be resized, which can be a costly operation.
- Therefore, an array-based stack is not inherently flexible for handling an indefinite number of values.
- Linked list-based stack:
- A linked list-based stack uses a linked list data structure to store the elements of the stack.
- Unlike an array-based stack, a linked list-based stack does not have a fixed size.
- Each element in the stack is represented by a node in the linked list, which contains a reference to the next node.
- This allows for dynamic allocation of memory, enabling the stack to handle an indefinite number of values.
- Adding or removing elements from a linked list-based stack is generally more efficient than resizing an array-based stack.
Based on these considerations, the more flexible representation for handling an indefinite number of values in a stack is the linked list-based stack (option b).

1. True or False: In a stack implemented using an array, the size of the stack is fixed, andelements can only be added or removed from the top of the stack.2. True or False: A stack implemented with a linked list can dynamically adjust its size toaccommodate an arbitrary number of elements.3. True or False: In a linked list-based stack, the last element added is the first element to beremoved (LIFO), similar to an array-based stack.4. True or False: The primary advantage of implementing a stack using a linked list is theelimination of memory wastage associated with a fixed-size array.5. True or False: When implementing a stack using a linked list, a pop operation involvesdeleting the element at the end of the linked list, opposite to a push operation, whichinserts a new element at the beginning.
