If the MAX_SIZE is the size of the array used in the implementation of circular queue, assume array index start with O, front points towards the first element in the queue, and rear points towards the last element in the queue. Which of the following condition specify that circular queue is Full ?

1. Front = rear = - 1
2.  Front = (rear + 1)%MAX_SIZE 
3.  Rear = front + 1
4.  Rear = (front + 1)%MAX_SIZE

 Front = (rear + 1)%MAX_SIZE 

 A circular queue uses an array in a circular manner, meaning when rear reaches the last index (MAX_SIZE - 1), it wraps around to 0 if there is space.

1. Front points to the first element, and rear points to the last element.
2. The queue is full when inserting another element would overwrite the front element.
3. This happens when the next position of rear (i.e., (rear + 1) % MAX_SIZE) is equal to front, indicating no space is left for a new element.
