Trie
A trie is a special rooted tree. that allows us to store a set of words by sharing their common prefixes.
Example # 1
Consider the following list of five words:
hello, jello, he, hello, jelly
The trie data structure for this list above is given below:
A trie node can be of three types:
- Root of the trie (shown as a diamond)
- Internal non-terminal node of a trie (white ovals)
- Word-ending node of a trie (green ovals).
Note: A word-ending node need not be a leaf. Also, such nodes are associated with a number that represents the frequency of the corresponding word.
Each trie edge is labelled with an alphabet.
Reading the words in the dictionary.
Starting from the root (diamond node), as we traverse a path along the trie, the letters along a path form a word. Whenever we encounter a word-ending node, we can stop and read off a valid word in the dictionary.
For instance, we note the correspondence between the list of words:
hello, hello, jello, he, jelly
and the paths in the trie.
Note: The word he is a prefix of the word hello. Therefore, in the trie, starting from the root, we see that a word-ending node corresponding to he is extended by the suffix “llo” to form a word-ending node for hello.
The frequency of occurrence of a word is the number associated with its corresponding word-ending node. Notice how the frequency of “he” is 1 but the frequency of “hello” is 2.
Finally, two words with a common prefix such as “jelly” and “jello” will share a common path corresponding to the prefix “jell” in the trie.
Trie Data Structure: Specification
A trie (or a prefix tree) data structure allows us to store a set of strings from a dictionary along with a frequency count for each strings. The following operations should be supported:
| Operation | Description | Return Type |
|---|---|---|
addWord(w) |
Insert a word w into the trie | None |
lookupWord(w) |
Return the frequency of w in the trie (0 if not present) | int |
autoComplete(w) |
Return a list of words in the trie along with their frequencies so that w is a prefix of each word in the list |
list of (str,int) |
Example : Adding Words to the Trie
We will illustrate the process of constructing a trie using an example.
At the beginning the empty trie is simply a root node:
Suppose we add the strings in the following order:
test, testament, testing, ping, pin, pink, pine, pint, testing, pinetree
| Trie | Operation |
|---|---|
 |
addWord(test) |
 |
addWord(testament) |
 |
addWord(testing) |
 |
addWord(ping) |
 |
addWord(pin) addWord(pink) addWord(pine) addWord(pint) addWord(testing) addWord(pinetree) |
Example: Trie Lookup
The operation lookupWord allows us to count the frequency of a word in a trie. If a word does not belong to a trie, then the frequency is 0.
For instance, consider the trie above:
lookupWord('test’) = 1 lookupWord('testing’) = 2 lookupWord('tesla’) = 0 lookupWord('tom’) = 0 lookupWord('pinetree’) = 1
Example: Autocomplete
The operation autoComplete provides a list of completions of a given string along with their frequencies.
autoComplete('pi’) = [ ('pin’,1), ('pink’,1), ('pine’,1),('pinetree’,1),('pint’,1), ('ping’,1) ] autoComplete('tom’) = [ ] # emtpy list because no word with prefix tom belongs to the trie autoComplete('testi’) = [ ('testing’,2) ]
Implementation
Your job is to implement the operations addWord, lookupWord and autoComplete in the class MyTrieNode defined below.
import sys
# We will use a class called my trie node
class MyTrieNode:
# Initialize some fields
def __init__(self, isRootNode):
#The initialization below is just a suggestion.
#Change it as you will.
# But do not change the signature of the constructor.
self.isRoot = isRootNode
self.isWordEnd = False # is this node a word ending node
self.isRoot = False # is this a root node
self.count = 0 # frequency count
self.next = {} # Dictionary mapping each character from a-z to
# the child node if any corresponding to that character.
def addWord(self,w):
assert(len(w) > 0)
# YOUR CODE HERE
# If you want to create helper/auxiliary functions, please do so.
return
def lookupWord(self,w):
# Return frequency of occurrence of the word w in the trie
# returns a number for the frequency and 0 if the word w does not occur.
# YOUR CODE HERE
return 0 # TODO: change this line, please
def autoComplete(self,w):
#Returns possible list of autocompletions of the word w
#Returns a list of pairs (s,j) denoting that
# word s occurs with frequency j
#YOUR CODE HERE
return [('Walter',1),('Mitty',2),('Went',3),('To',4),('Greenland',2)] #TODO: change this line, pleaseDescription of MyTrieNode Class
A trie node structure has the following attributes/fields:
isRootA Boolean flag denoting if the node is a root.isWordEndA Boolean flag denoting if the node is the word ending node.countA count field for frequency count for a word ending node.next:A dictionary that maps from each of the alphabets ‘a’ – ‘z’ to the child node corresponding to the alphabet.
# The original example: let us see if the code works
t= MyTrieNode(True) # Create a root Trie node
lst1=['test','testament','testing','ping','pin','pink','pine','pint','testing','pinetree']
# Insert the words in lst1
for w in lst1:
t.addWord(w)
# Perform lookups
j = t.lookupWord('testy') # should return 0
j2 = t.lookupWord('telltale') # should return 0
j3 = t.lookupWord ('testing') # should return 2
# Run autocompletes
lst3 = t.autoComplete('pi')
print('Completions for "pi" are : ')
print(lst3)
lst4 = t.autoComplete('tes')
print('Completions for "tes" are : ')
print(lst4)Completions for "pi" are :
[('Walter', 1), ('Mitty', 2), ('Went', 3), ('To', 4), ('Greenland', 2)]
Completions for "tes" are :
[('Walter', 1), ('Mitty', 2), ('Went', 3), ('To', 4), ('Greenland', 2)]
