3.) The function remove of the class arrayListType removes only the first occurrence of an element. Add the function removeAll as an abstract function to the class arrayListType, which would remove all occurrences of a given element. Also, write the definition of the function removeAll in the class unorderedArrayListType and write a program to test this function.
