trying to make a code that can convert numbers to descending order using 1-4 numbers

using System;<br><br>class Program<br>{<br> static void Main()<br> {<br> Console.WriteLine("1-4 digits to descending order");<br><br> string input = Console.ReadLine();<br><br> int[] array = new int[4];<br> array[0] = int.Parse(input[0].ToString());<br> array[1] = int.Parse(input[1].ToString());<br> array[2] = int.Parse(input[2].ToString());<br> array[3] = int.Parse(input[3].ToString());<br><br> for (int i = 0; i < 4; i++)<br> {<br> for (int j = 0; j < 4; j++)<br> {<br> if (array[i] < array[j])<br> {<br> int saved = array[i];<br> array[i] = array[j];<br> array[j] = saved;<br> }<br> }<br> }<br> string amogus = array[0].ToString() + array[1].ToString() + array[2].ToString() + array[3].ToString();<br> Console.WriteLine(amogus);<br> }<br>}
