Implement a function called merge that does the following in C#:

* Takes three sequences of numbers from 1 to 15

* Merge the list with members that adhere to the following requirements

* Any multiple of 3

* Is a member of all three lists

Explanation:

First get a list of multiples of three from all three lists (no repeats)

Then combine the list of threes with the intersection of all three lists (no repeats)

public class Problem2

{

public static IEnumerable merge(IEnumerable input1, IEnumerable input2, IEnumerable input3)

{

}

}

static void Main(string[] args)

{

Random rnd = new Random();

var list1 = Enumerable.Range(1,10).Select(i=>(rnd.Next()%15)+1);

var list2 = Enumerable.Range(1,10).Select(i=>(rnd.Next()%15)+1);

var list3 = Enumerable.Range(1,10).Select(i=>(rnd.Next()%15)+1);

var answer = Problem2.merge(list1,list2,list3);

foreach( int i in answer )

{

Console.WriteLine(i);

}

}
