In c++ write a program that will read lines from a text file put each line in a doubly linked list in reverse order then then put those lists in a main doubly linked list and reverse that one too.

ex file:

abc 123

efg 123

Expected results:

Reversed DLL:

NULL <-123<->abc<->NULL

NULL<-123<->efg<->NULL

Reversed main Doubly linked list of doubly linked lists:

NULL<- [NULL<-123<->efg<->NULL]->NULL

NULL<- [NULL <-123<->abc<->NULL]->NULL

DO NOT USE #include!!
