HashMap implementation in React

In this project, I have implemented an HashMap class which has the following functionalities -

void put(key: number, value: number) inserts a (key, value) pair into the HashMap. If the key already exists in the map, update the corresponding value.
number get(key: number) returns the value to which the specified key is mapped, or -1 if this map contains no mapping for the key.
void remove(key: number) removes the key and its corresponding value if the map contains the mapping for the key.

Installation

Pull this branch into your local system.
Make sure you have Node installed (preferrably Node v18.17.1).
Navigate to the project directory and run
```
npm install
```
Once all the dependencies have been installed, run the following command to start the dev server.
```
npm run dev
```
