Today is not my coding day. I have a problem I should be able to design
a solution for an am struggling. Clearly I am missing "something"
I have 2 lists (LISTNEW and LISTOLD) of the following format:
ParentA
<space>Child 1
<space>Child 2
<space>etc.
ParentB
<space>Child 1
<space>etc.
etc.
The parents are in alphabetical sorted order, the children may not be in
sorted order
I need to hunt through LISTOLD comparing the LISTOLD Parents to the
LISTNEW Parents
FOR any LISTOLD Parent present in LISTNEW, check the Children of the
matching Parents and add any Child for the LISTOLD Parent that is not
already under its matching LISTNEW Parent
FOR any LISTOLD Parent NOT in LISTNEW, I can ignore the Parent and
its Children
I can not seem to write an approach to solve this today. Does any body
have some code so solve this they may be willing to share?
