let's _use_ an object-oriented data structure
maybe to plot a graph.
this is hard for me to do now.
oh no what language.
maybe python because i'm familiar with it.
class Node:
def __init__(self, parent = None):
self.children = []
self.parent = parent
y'know, this is so hard for me to do, maybe I should get to know a data structures library in every language.
