Onsite Interview 1 a): Write a program to check whether a number is prime . Additional constraints consider negative primes etc.

b) some kind of list merge problem

A list of lists eg : [A,B,C] // unsorted

A= [1,2,3]
B=[2,3]
C=[1,2]

Start with List in reverse alphabetical order
eg:C merge with B removing duplicates then merge this with A doing the same .

Optimize solution

c) Intersection of two Integer lists ?
