Question

I’m trying to reorganize an array based on the first occurrence of a value (thus simulating similar functionality to a circular array.)

For example, in the following array I wish the first occurrence of the value 6 to become the new first element, and prior elements to become the latter:

So:

int[] myArray = {2, 3, 6, 1, 7, 6};

Becomes:

myArray = {6, 1, 7, 6, 2, 3};

What is the “best” way to achieve this?

Answer 1

int[] myArray = { 2, 3, 6, 1, 7, 6 };
myArray = myArray
            .SkipWhile(i => i != 6)
            .Concat(myArray.TakeWhile(i => i != 6))
            .ToArray();

Should do the trick!

You will need a using System.Linq;
