- Krishna May 31, 2015Every trie node will store the counts of the words that end with it ( the count will be 0 if it is not a leaf ).
Ex. Hi John ! How are you ? Hi Jane, I'm doing good. Hiya everybody, how's the party ?
will have a node structure for H(0) --> i (2) --> y (0) --> a (1)
This will conserve space and worst time complexity will be O(K) where K is the maximum number of alphabets in that structure.
