@vin101 WHY REAR AT 3 ?????

REAR POINTS TO POSITION WHERE NEXT ELEMENT HAS TO BE INSERT.

 SO WHY 3

---

Well it's a matter of adopting a convention to disambiguate between queue empty and full conditions
Also after inserting at 2nd index rear points to next position where element has to be inserted hence 3.
