Generic BubbleSort Extension

Question

    public static T[] BubbleSort(this T[] arr) where T : class
    {
        for (int i = 0; i < arr.Length; i++)
        {
            for (int j = 0; j <         


        

Answer 1

You can't use < on type parameters. So you could use Comparer.Default.

Or you could just add a generic contraint that requires T to implement IComparable. Then you can call the Compare method.

In addition your j loop is off by one. You either need to compare&swap arr[j] and arr[j+1] or change the lower bound to 1 and the upper to arr.Length
