Hello Candidate

Welcome to the "zoo", please help to complete the coding in this project according to the following requirements within 45 minutes.

Task A: Digest Report

Managing a zoo is never an easy job, so we have created a profile for each of the animals in the zoo like below, you can call GET /zoo/animals to get all raw data.

{
   "id": "a000001",
   "name": "Lulu",
   "category": "MOUSE",
   "height": 0.05,
   "weight": 0.5,
   "sourceCountry": "China",
   "birthTime": 1623919916000,
   "statue": "ALIVE"
}

Now, we want you to aggregate these raw data and convert to a digest report like below, and provide an API in the ZooController to return the result.

{
   "overall": {
      "aliveCount": 3,
      "deadCount": 1,
      "lightestOne": "AaAa",
      "shortestOne": "BbBb",
      "oldestOne": "CcCc"
   },
   "size": {
      "Small animal count": 1,
      "Medium animal count": 1,
      "Large animal count": 1
   },
   "sourceCountry": {
      "China": 1,
      "Mexico": 1,
      "...": 1
   },
   "category": {
      "Mouse": 1,
      "Ox": 1,
      "...": 1
   }
}

Notes

• We already had provided methods in ZooClient under dao folder to query all animals, you can use them to get the raw data you need
• In Size, sourceCountry, category these three sections in the JSON body, we only count alive animals. In other words, the summation of all items under each of them should equal the value of overall.aliveCount.
• In Size section, animal size definition matrix as below:

  Size category	weight
  Small animal	30 <
  Medium animal	30 <= && < 150
  Large animal	150 <=

• The sequence under sourceCountry should be natural ordering.
• The sequence under category should according to the index value of AnimalCategory in ASC.
• Please make the code clean, elegant, efficient as possible as you can.

Task B: Animal talent show

To keep the zoo consistently running, we need to let these animals play some talent show to earn money. However, different animals have different performances, so please work out an API to response different value according to the different AnimalCategory in request params.

Notes

• Please use factory design pattern to implement the API.
• Please make sure the API can meet following 2 cases, no need to extends to other cases. Request: GET /zoo/show?cagetory=DOG -> Response: Bark bark! Request: GET /zoo/show?cagetory=MONKEY -> Response: Tell a joke!

Task C: RESTful API for animal management

To better manage the animals, we need a series of RESTful APIs to add/delete/update/query the animals in the zoo. Please help to provide these APIs in the ZooController, just declare them, no implement.
