On the same path
You have to write a function that receives a tree – potentially large but finite –
and a list of pairs of tree's nodes.
For each pair, you must determine if the two nodes are on a same path (True) in the tree or not (False),
then return an iterable/list of these booleans.
Input: two arguments:
- a tree as a tuple (a node, list of sub-trees)
- a list of pairs (the tuples of two nodes)
Output: An iterable/list of booleans.
Example:
on_same_path( ('Me', [('Daddy', [('Grandpa', []), ('Grandma',...
