Six toys; A1, A2, A3. A4, A5 and A6 are kept around a circular pattern (not necessarily in the same order). A4 is second to the left of A6.  A5 is to the immediate left of A2.  A1 is second to the right of A3.  A3 is to the immediate right of A4. If we  start counting the number of toys towards the left of A5, then how many toys are kept between A6 and A5 ?
