Write a simple server, which provides a RESTful API. It should implement these two API calls:
GET /user/{id} Returns user details based on the id. You can return static mock results. PUT /user/{id} Modifies a user property. It's ok to only store changes in memory.
A simple SpringBoot application has been created with 2 rest endpoints (together with a generic home restpoint). I have decided
to create some sample data via a script here: /resources/demo_data.sql. The script can be run through the h2 console at /h2-console.
Given the input string: "Hello world! How (sp?) are you today (;" split it into a list of words. You must strip all punctuation except for emoticons. Result for example: ['Hello','world', 'how', 'sp', 'are', 'you', 'today', '(;']
