Palindrome

A Restful API to resolve the pallindrome challenge

Frameworks and Technologies

• Java v 1.8
• Dropwizard
• Hibernate validator
• Maven v 3.3

How to use

• Go to palindrome.api folder (cd palindrome.api/ )
• Compile the application typing: mvn clean install
• After that, you can run the application. Type: java -jar target/palindrome.api-1.jar server palindrome-configuration.yml
• Use a REST client application such as Postman. Then, do the following GET operations:
  • http://localhost:9000/palindrome/v1/range?min=1&max=1000000
    In the previous version, it works well if the maximum value is less than or equal to 1 million
  • http://localhost:9000/palindrome/v2/range?min=1&max=1000000
    In the newest version, It is suggested if the maximum value is greater than 1 million because it gets the result in a parallel manner.
• They both return a JSON with the following structure:

{
  "palindromeStrings": {
    "decimal_number": "binary_number",
    ..
  },
  "iterations": iterations_needed_to_get_palindromes_in_the_range,
  "bigOComplexity": "An explanation about the complexity to calculate palindromes in the range"
}
