You can check your code it is not matching for sample test case also.
I think your prime function is also wrong, you are checking prime for arr[i] but initially there is nothing present in arr[].
The default size for arr[], stack a and b does not mean anything, it is not matching with given constraints. Also q nothing is said so you can taking something by yourself, take it after getting the input of q.

Tip:- better use sieve() for precomputing and storing some prime numbers.
