Write a program to print all the elements of an array in forward and backward order using single loop. ARRAY is 1,2,3,4,5 output should be 1,2,3,4,5,5,4,3,2,1

for (int i = 0; i < arr.Length*2; i++)
{
if (i > arr.Length-1)
{
Console.Write(arr[(arr.Length*2-i)-1] + "\t");
}
else
{
Console.Write(arr[i]+"\t");
}

int[] array = { 1, 2, 3, 4, 5 };
foreach (int value in array)
{
Console.WriteLine(value);
}
Array.Reverse(array);
foreach (int value in array)
{
Console.WriteLine(value);
}
Console.ReadLine();
