Hi,
I was wondering if anyone had a binary search tree
module I could use? I need to write a program that
counts the number of occurrences of each word in a
file, and outputs the word and corresponding counts
alphabetically. For example, if input is
Have a nice day. Have a nice day.
Have a nice day.
Have a nice day.
the output is
a 4
day 4
have 4
nice 4
The code has to be modular based on classes. I'm
thinking of making a
tree node that looks like this
bintree[ [key, data], left, right] ,
where I can traverse the tree by simply incrementing
the current root
to the appropriate child.
temp = bintree.root
temp = temp[1] #move to the left child.
temp = temp[2] #move to the right child.
but I don't know how to implement it correctly using
classes. (i.e
using def __init__(self), etc)
I'm new to this python language so I would appreciate
anyone's help.
Thanks in advance :)
Christy
