For this micro assignment, you must implement two Linked List functi.docx

For this micro assignment, you must implement two Linked List
functions. We will use the following
example Linked List:
2 0 -1 5 7
getElementAt(index)
This function should return the element (i.e. value) of the Nth
item inside the linked list. For example,
on the Linked List above, getElementAt(0) should return 2;
getElementAt(3) should return 5.
addElementAt(value, location)
This function should insert a new value at the given location.
Note that the location supplied must be
within bounds of the LinkedList. For example, we cannot call
addElementAt(4, 11) on the above Linked
List because 11 is beyond the size of the Linked List.
Here are some examples. If we call addElementAt(0, 1), the
above Linked List would now look like:
1 2 0 -1 5 7
If we again call addElementAt(2, 123), we would get:
1 2 123 0 -1 5
7

Grading
Your submission will be graded based on the following:
1. [7] Your solution does not cause any runtime issues and your
file passes all test cases
2. [3] Your code contains good style. For example,
ble names
