I have a small array of ints. I want to reorder the array from largest to smallest. Is there a method to do this?
You could use Array.Sort :
int[] array = new[] { 1, 3, 2 };
Array.Sort(array, (x, y) => y.CompareTo(x));
As far as complexity is concerned:
On average, this method is an O(n log n) operation, where n is the Length of array; in the worst case it is an O(n ^ 2) operation
You can try something like this
int[] ints = new int[] {1, 2, 3, 4, 1, 2, 3};
var sorted = ints.OrderBy(i => i);
Found at Sort array of items using OrderBy<>
You can do it using Array
Sort
& Reverse
:
Array.Sort(array);
Array.Reverse(array);
Example:
[Test]
public void Test()
{
var array = new[] { 1, 3, 2 };
Array.Sort(array);
Array.Reverse(array);
CollectionAssert.AreEquivalent(new[] { 3, 2, 1 }, array);
}
