Your task in this exercise is to show the behavior for adding elements to an array-based list.
In the array displayed below, your task is to add add_value at position add_pos.
To move an element, click on it (to highlight it), then click on where you want it to go. You can insert the new value add_value into a highlighted array position by clicking the "Add" button.
To shift elements one position to the right, the first step could be swapping element arr_size-1 with position arr_size
Then, keep swapping element i with i+1 until you make the insertion position empty for insertion
