Question { Intel, 39533 }

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).

Answer

main ()
{

int a[] = { 1, 1, 3, 3, 3, 5, 5, 5, 9, 9, 9, 9 };
int i = 0, key;
int size;

size = sizeof (a) / sizeof (int);
key = a[i];

for (; i < size; i++)
{
if (key != a[i])
{
printf ("\n %d", a[i]);
key=a[i];
}
}
}
