Implement a dictionary using Trie such that if the input is a string representing a word, the program prints its meaning from the prebuilt dictionary.
Input: str = “map”
Output: a diagrammatic representation of an area
Input: str = “language”
Output: the method of human communication
Approach: We can use a Trie to efficiently store strings and search them. Here, an implementation of a dictionary using Trie (memory optimization using hash-map) is discussed. We add another field to Trie node, a string which will hold the meaning of a word. While searching for the meaning of the required word, we search for the word in Trie and if the word is present (i.e isEndOfWord = true) then we return its meaning otherwise we return an empty string.
Below is the implementation of the above approach:
a diagrammatic representation of an area
