- Now, the first two elements are sorted. Take the third element and compare it with the elements on the left of it.
- Similarly, place every unsorted element at its correct position.
How do you add numbers to an array?
- First get the element to be inserted, say x.
- Then get the position at which this element is to be inserted, say pos.
- Then shift the array elements from this position to one position forward, and do this for all the other elements next to pos.
- 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).
