I need to add an element to Array specifying position and value.
For example, I have Array
int []a = {1, 2, 3, 4, 5, 6};
after applying addPos(int 4, int 87)
it should be
int []a = {1, 2, 3, 4, 87, 5};
I understand that here should be a shift of Array's indexes, but don't see how to implement it in code.
