What will be the output of the following C# code?

static void main(string[] args)
{
    int []arr = new int[]{ 1, 2, 3, 4, 5};
    fun (ref arr);
    for (int i = 0; i < arr.Length ; i++)
    Console.WriteLine( arr[i] + "  ");
}
static void fun(ref int[]a)
{
    a = new int[6];
    a[3] = 32;
    a[1] = 24;
}
