Easiest way to Rotate a List in c#

Question

Lists say I have a list List {1,2,3,4,5}

Rotate means:

=> {2,3,4,5,1} => {3,4,5,1,2} => {4,5,1,2,3}

Answer 1

You can use below code for left Rotation.

List backUpArray = array.ToList();

for (int i = 0; i < array.Length; i++)
{
    int newLocation = (i + (array.Length - rotationNumber)) % n;
    array[newLocation] = backUpArray[i];
}
