WHAT IS CORRECT ANSWER

Question

https://gateoverflow.in/17423/isro2014-36

WE WILL START INSERING FROM q[2] OR FROM q[3]

Answer 1

See 2 comments are there,

Comment 1: we initialize front and rear as -1, so first element should be inserted at q[2].

Comment 2: Correct. So when we initialize to -1, the element is inserted at [0].

The question says

The front and rear pointers are initialized to point at q[2]

So, element is inserted at q[3]

I hope you understand
