How do you add numbers to an array?

Approach:

1. First get the element to be inserted, say x.
2. Then get the position at which this element is to be inserted, say pos.
3. Then shift the array elements from this position to one position forward, and do this for all the other elements next to pos.
4. Insert the element x now at the position pos, as this is now empty.

Why is adding and removing from a sorted array O N?

The insertion and deletion of elements in a sorted array executes at O(n), due to the need to shift all the elements following the element to be inserted or deleted; in comparison a self-balancing binary search tree inserts and deletes at O(log n).
