You’ve got the basic idea correctly. In a trie data structure, each node represents a character in a word or a path. Here’s a more detailed breakdown of your example with the word “Tommy” in a trie:

– The root node is typically an empty string, representing the beginning of the trie.
– For the word “Tommy”:
1. The first character ‘T’ would be represented as a child of the root node.
2. The second character ‘o’ would be a child of the ‘T’ node.
3. The third character ‘m’ would be a child of the ‘o’ node.
4. The fourth character ‘m’ would be a child of the previous ‘m’ node.
5. Finally, the fifth character ‘y’ would be a child of the second ‘m’ node.
– At the node representing ‘y’, the `is_word` flag is set to `true` to indicate that the path from the root to that node represents a complete word, in this case, “Tommy.”

You are correct that for each node in the trie, there is an `is_word` flag to indicate whether the path to that node represents a complete word. Additionally, there’s an array of pointers (typically one for each letter in the alphabet, though in practice, it might be optimized to only have pointers for characters that are present in the dataset) to represent the children of that node.

In your explanation, the representation of the word “Tommy” in the trie is accurate, with the last node having all of its children set to NULL and the `is_word` flag set to `true` to signify that “Tommy” is a valid word in the trie.
