Insert - USE

Insert[Object, List, Position]: Creates a new list with the object inserted into the list at the given position.

Example: Insert[x^2, {1, 2, 3, 4, 5}, 3] places x² at the third position and creates the list {1, 2, x², 3, 4, 5}.
- We point out that this last list is garbage:

In the applet below: list3=list1-1={0,1,2,3,4} is well-defined but list3=list2-1={} is empty.

Note: If the position is a negative number, then the position is counted from the right.

Example: Insert[%bgr%37%%, {1, 2, 3, 4, 5}, -1] places x² at the end of the list and creates the list {1, 2, 3, 4, 5, 37}.

[Insert[List 1, List 2, Position]: Inserts all elements of list1 in list2 at the given position.

Example: Insert[{11, 12}, {1, 2, 3, 4, 5}, 3] places the elements of list1 at the third (and following) position(s) of list2 and creates the list {1, 2, 11, 12, 3, 4, 5}.

Note: If the position is a negative number, then the position is counted from the right.

Example: Insert[{11, 12}, {1, 2, 3, 4, 5}, -2] places the elements of list1 at the end of list2 before its last element and creates the list {1, 2, 3, 4, 11, 12, 5}.
