Please, 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 Array List 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.
