To run, simply execute the mvnw (or mvnw.cmd if you're on windows) executable like so:
./mvnw spring-boot:run
or
./mvnw.cmd spring-boot:run
To test, you could send requests to the api using curl or httpie as so:
curl -X POST -H "Content-Type: application/json" -d '{"input": "<s>"}' localhost:8080/api/<p> -w "\n"
or
echo '{"input": "<s>"}' | http POST localhost:8080/api/<p>
where <s> is the input string you'd like to test and <p> is the part you are testing, either part1 or part2.
You could also test my project by adding to the testcases I wrote, provided in src/test/java/dev/banisomo/elmersWebAPI.
