Revise this code example C# for Finding the duplicates and follow the discussion question below. Apart from code, the writing part is just 150 words
//function to display the duplicate values in an Array
public void DisplayArray(ArrayList ary)
{
//loop through all the elements
for (int i = 0; i < ary.Count; i++)
{
Console.Write(ary[i]+” “);
}
Console.WriteLine();
}
//function to find the duplicate values in an Array
public void FindDuplicate(ArrayList ary)
{
//Array list to store all the duplicate values
ArrayList dup = new ArrayList();
for (int i = 0; i < ary.Count;i++)
{
for (int j =i+1; j < ary.Count; j++)
{
//compare each value with following remaining values
if (ary[i].Equals(ary[j]))
{
//When duplicate value is found, check
//whether the value not contained in the dup array list
if(!dup.Contains(ary[i]))
{
//if not contains, then add the value to dup array list
dup.Add(ary[i]);
}
}
}
}
Console.WriteLine(“The numbers which duplicates are”);
DisplayArray(dup);
}
=======================================
//Input Arraylist values: 4,5,2,5,4,7
Output: 4 5 2 5 4 7
The numbers which are duplicates:
4 5
DISCUSSION TOPICS
After reading week 2 required materials and conducting independent research as needed, discuss with your peers the following:
- The solution uses an ArrayList object. Modify it and make it run with code that uses a different approach to solve the problem with identical results:
- post an alternative solution(it must run on Visual Studio)
- explain what is different and how it works
- compare the ArrayList approach with the alternative solution, evaluate which one is more effective, and explain why.
