  Part 3: Redo Part 1 on the linkedListType.h. You cannot use any predefined member function. All your modifications should be performed inside the header file linkedListType.h that is attached with this assignment. After performing the modifications, you should run the file memberLinkedList.cpp (attached with this assignment) without modifying it without any problems and you should get the following output: List L before LincrementByConstant(3) contains: 2134530 List Lafter L.incrementByConstant(3) contains: 5467863 List L before L.sortEach2('a') contains: 21 345 30 List Lafter L.sortEach2('a') contains: 1 2 3 4 350 List L before L.sortEach2('d') contains: 2134530 List Lafter L.sortEach2('d') contains: 214 3530 List L before L.duplicate Orremove(3) contains: 2134530 List Lafter L.duplicate Rremove(3) contains: 344553 List L before L.split(3, L1,L2) contains: 2134530 List Lafter L.split(3,L1,L2) contains: 2134530 List L1 after L.split(3,L1,L2) contains: 210 List L2 after L.split(3,L1,L2) contains: 3453  Part 3: Redo Part 1 on the linkedListType.h.
