	// Motivation:
	//
	// We do not store count of items in the queue to avoid mutual blocking of enqueue and dequeu operaions.
	// In the current implementation enqueue and dequeue do not block each other,
	// but simultaneous calls of the same operations will be blocking.
	//
	// Alos we allocate array with size N + 1 to the logical capacity of the queue N,
	// this is made to distinguish between cases when the queue is empty or full
