    Take a look at Data.List and the function subsequences.<br>
<a class="moz-txt-link-freetext" href="http://www.haskell.org/ghc/docs/7.0.2/html/libraries/base-4.3.1.0/Data-List.html#v:subsequences">http://www.haskell.org/ghc/docs/7.0.2/html/libraries/base-4.3.1.0/Data-List.html#v:subsequences</a><br>

    The only thing you'll need to figure out after that is how to
    transform all of those strings to a list data type.<br>
    <br>
    I hope this helps,<br>
