Solution By Steps

Step 1: Initialization The queue is initialized with a static array of size 4. The front is set to 0, the back to -1, and the current size to 0.

Step 2: Enqueue Operation To enqueue an element:

1. Increment the back index by 1.
2. Set the element at the back index in the static array to the new element.
3. Increment the current size by 1.

Step 3: Dequeue Operation To dequeue an element:

1. Store the element at the front index.
2. Increment the front index by 1.
3. Decrement the current size by 1.
4. Return the stored element.

Step 4: Is Empty Check To check if the queue is empty:

1. Return True if the current size is 0, else return False.

Step 5: Is Full Check To check if the queue is full:

1. Return True if the current size is equal to the size of the static array, else return False.

Final Answer

The Queue class is initialized with a static array of size 4, with front at 0, back at -1, and current size at 0. It supports enqueue, dequeue, isEmpty, and isFull operations.

Key Concept

Queue Operations

Key Concept Explanation

A queue is a data structure that follows the First In First Out (FIFO) principle. Enqueue adds elements to the back, dequeue removes elements from the front, isEmpty checks if the queue is empty, and isFull checks if the queue is at maximum capacity. These operations are fundamental in managing data in a sequential manner.
