Write, efficient code for extracting unique elements from
a sorted list of array.
e.g. (1, 1, 3, 3, 3, 5, 5, 5, 9, 9, 9, 9) -> (1, 3, 5, 9).

#include<stdio.h>
main()

int a[] = {1, 1, 3, 3, 3, 5, 5, 5, 9, 9, 9,10};
int cur = 0;

for (i = 1 ; i < (sizeof(a)/4) ;i++)
{
if ( a[cur] != a[i])

private int[] GetUniqueList(int[] A)
{
if(A == null ) return null;
List<int> result = new List<int>();
for(int i=0;i<A.Length-1;i++)
{
if (A[i] != A[i + 1]) result.Add(A[i]);
}
if(A.Length>0)
result.Add(A[A.Length-1]);
return result.ToArray();
