c++ linked list

i have a file ([login to view URL]) with two columns separated by a comma. column one is a node, and column two is column one's parent node. so in reality, this file is a tree represented as two columns. i need to convert this file into something that makes sense visually. see [login to view URL] ... this is ultimately what i want [login to view URL] to look like. the ':' at the end of the line indicates the end of the branch. Please see the image attached for a visual. i think this proj can easily be done in cpp treating both cols as strings and using a linked list ... i just don't have the time. i need this asap !! ## Deliverables please see .zip
