When would it be more advantageous to use a linked list implementation of a queue over an array-based implementation?
When dynamic resizing and the potential for overflow are concerns.
When memory usage needs to be tightly controlled.
When the maximum number of elements in the queue is known in advance.
When dealing with a small, fixed number of elements.
How do you efficiently handle the situation where the array representing the queue becomes full?
Resize the array to accommodate more elements.
Stop accepting new elements.
Use a linked list instead of an array.
Delete the oldest element.
What is the role of the 'front' pointer in a queue data structure?
It points to the location where the next element will be added.
It determines if the queue is full or not.
It keeps track of the total number of elements in the queue.
It points to the element that has been in the queue the longest.
What value does the 'isEmpty' operation on a queue return if the queue contains no elements?
0
True
The first element in the queue
-1
What is the main advantage of using a circular array for implementing a queue compared to a regular array?
Efficient utilization of space after multiple enqueue and dequeue operations
Reduced memory consumption
Better handling of sorted data
Faster access to individual elements
What is the primary disadvantage of using an array to implement a queue?
High memory usage
Complex implementation
Fixed size limitation
Inefficient search operations
What is the maximum number of elements a circular queue of size 'n' can hold?
n + 1
It depends on the implementation
n - 1
n
What is the time complexity of enqueue and dequeue operations in a well-implemented array-based queue?
O(1)
It depends on the size of the array.
O(n), where n is the number of elements in the queue.
O(log n)
How does an array-based queue handle the underflow condition?
By using a circular array to reuse the empty spaces.
By raising an exception or returning an error value when attempting to dequeue from an empty queue.
By dynamically resizing the array.
By overwriting the existing elements.
What is the primary difference between a queue and a stack?
Queues use FIFO (First-In-First-Out), while stacks use LIFO (Last-In-First-Out).
Queues are linear data structures, while stacks are non-linear.
Queues use LIFO (Last-In-First-Out), while stacks use FIFO (First-In-First-Out).
Queues store numbers, while stacks store characters.
