Write the condition for empty and full circular queue

A circular queue is a linear data structure that follows the FIFO (First In First Out) principle but wraps around upon reaching the end of the array which stores the data.

1. Condition for an Empty Circular Queue: A circular queue is considered empty when the front and rear pointers are at the same position. In other words, if we denote the front and rear pointers as 'front' and 'rear' respectively, the condition for an empty circular queue can be written as:

   if (front == rear)

2. Condition for a Full Circular Queue: A circular queue is considered full when the rear pointer is one position behind the front pointer. However, because the queue is circular, we must take into account the possibility that the rear pointer wraps around to the beginning of the array. Therefore, the condition for a full circular queue can be written as:

   if ((rear + 1) % size == front)

Here, 'size' is the size of the array that is used to implement the circular queue. The modulus operator (%) is used to ensure that the rear pointer wraps around to the beginning of the array when it reaches the end.
