Micronaut AWS API gateway for generating and solving sudokus

A project to try out AWS lambda for an API using Java Micronaut. Based on the example here.

To run locally use SAM Local:

$ sam local start-api --template sam-local.yaml

Two GET endpoints are provided: /generate/{boxHeight}/{boxWidth}/{difficulty} and /solve/{boxHeight}/{boxWidth}/{puzzleNumbers}.

Examples:

$ curl -s http://127.0.0.1:3000/generate/3/3/tricky

returns

{
  "puzzleNums": [0,0,0,0,5,7,...,0],
  "solution": [2,3,8,4,5,7,...,3],
  "numberOfSolutions": "SINGLE_SOLUTION",
  "difficulty": "TRICKY"
}

For solving use any of:

$ curl -s http://127.0.0.1:3000/solve/3/3/0,0,0,0,5,7,  ...
$ curl -s http://127.0.0.1:3000/solve/3/3/000057  ...
$ curl -s http://127.0.0.1:3000/solve/3/3/....57  ...

The possible puzzle layouts are box sizes 2x2, 2x3, 2x4, 2x5 and standard 3x3. Difficulties can be easy, medium, tricky or fiendish although not all combinations are available.
