• Get a single Fibonacci Number at position n

Deploy

Prerequisites

Tested with the following environment

Windows 10
MacOS 10.11.6
Git 2.10.1 or above
Maven 3.2.5 or above
JDK 1.8

Get source code

$ mkdir inteview
$ cd inteview
$ git clone https://github.com/gaochenyue/fibonacci.git

build

$ cd fibonacci
$ mvn clean package

The first build will take longer because it has to download dependencies

If you don't want to build your own, you can directly download the pre-built JAR file here

start the server

$ java -jar target/fibonacci-1.0.0.jar

Usage

Home page with REST API instruction and Examples

http://localhost:8080/

REST API to get fibonacci sequence at position n

GET http://localhost:8080/fibonacci/sequence/{n}

n is the position of fibonacci number. It should be an positive integer

Sample Response

{
  "fibonacciSequence" : [ {
    "position" : 0,
    "value" : 0
  }, {
    "position" : 1,
    "value" : 1
  }, {
    "position" : 2,
    "value" : 1
  }, {
    "position" : 3,
    "value" : 2
  } ]
}

REST API to get fibonacci number at position n

GET http://localhost:8080/fibonacci/number/{n}

n is the position of fibonacci number. It should be an positive integer

Sample Response

{
  "position" : 6,
  "value" : 8
}
