Breadcrumb Generator

We would like you to implement a breadcrumb menu generator. Specifically, to create a function that takes a URL and a separator (see below) and returns a string representing each element of the HTML required to render a breadcrumb linking to each page.

menu Example Breadcrumb menu

Examples

1
breadcrumb_function("https://www.btplc.com/SITES/ADASTRAL.HTML", " : ")

Should return:

<a href="/">HOME</a> : <a href="/SITES/">SITES</a> : <span class="active">ADASTRAL</span>
2
breadcrumb_function("https://www.btplc.com/careercentre/Technology.htm", " / ")

Should return:

<a href="/">HOME</a> / <a href="/careercentre/">CAREERCENTRE</a> / <span class="active">TECHNOLOGY</span>
3
breadcrumb_function("https://www.btplc.com/careercentre/vacancies/Technology.htm", " : ")

Should return:

<a href="/">HOME</a> / <a href="/careercentre/">CAREERCENTRE</a> / <a href="/careercentre/vacancies/">VACANCIES</a> / <span class="active">TECHNOLOGY</span>
4
breadcrumb_function("https://www.btplc.com/careercentre/index.htm", " : ")

Should return:

<a href="/">HOME</a> : <span class="active">CAREERCENTRE</span>

Requirements:

  • Element text should be in uppercase.
  • Your function should work for any number of sub-pages. The URL should build as shown in example 3.
  • Each element should be separated by a user entered separator.
  • Ignore anchors and parameters.
  • The last element can terminate in an extension (.html, .htm, .php, etc. ).
  • You will always be provided a valid url – You don’t need to validate them.

Tips:

  • Use the language you’re most comfortable working in
  • Evidence of testing is good
  • If, for some reason you aren’t able to complete it, concentrate on the quality of the parts you complete, rather than producing a bad implementation of the whole thing.
  • There’s no need to implement a CLI, web interface or anything more complicated than a simple procedure/method/function.
    • But you’re welcome to write a wrapper if you like (eg if it helps with testing).
  • We're not expecting this to take you more than an hour or so.
  • Feel free to use existing libraries if appropriate.
  • When you attend the interview, please join on a laptop where you can run/edit your code as you will be asked to make a modification during the interview.
