🛠️ How to Use

Follow these steps to use this project:

1. Clone this repository to your local machine:
   git clone https://github.com/muditm006/TextAutocomplete.git cd TextAutocomplete

2. Compile all .java files using your preferred Java compiler:
   javac *.java

3. Run the AutocompleteTest.java, HashMapTest.java, or TrieTest.java files to test individual components: java AutocompleteTest

4. Integrate Autocomplete.java into your application by providing it with a dataset (e.g., words or numbers) as input. Use its methods to retrieve autocomplete suggestions based on user queries.
