lab-The function removeAt of the class arrayListType removes an element

Do the lab in c++

1- The function removeAt of the class arrayListType removes an element

from the list by shifting the elements of the list. However, if the element to be
removed is at the beginning of the list and the list is fairly large, it could take a
lot of computer time. Because the list elements are in no particular order, you
could simply remove the element by swapping the last element of the list with
the item to be removed and reducing the length of the list. Rewrite the
definition of the function removeAt using this technique.

2- The function remove of the class arrayListType removes only the first
occurrence of an element. Add the function removeAll to the class
arrayListType that would remove all occurrences of a given element. Also,
write the definition of the function removeAll and a program to test this function.

3- Add the function min to the class arrayListType to return the smallest
element of the list. Also, write the definition of the function min and a
program to test this function.

4-Add the function max to the class arrayListType to return the largest
element of the list. Also, write the definition of the function max and a
program to test this function.
