Unfortunately (unfortunate because it is clever and short) -- I believe your solution is flawed.

Using the words 'aabcc' and 'abbbc', your code suggests that the words have 5 characters in common. The original poster was vague about the requirements, however, I suspect that if both words have 5 characters, a declaration that the words have 5 characters in common, with different words, may be unexpected.

With this in mind, I suggest that your first example is correct if the goal is to determine the sum of the number of characters that is in each word that are also in the other word (probably not what the original posted wanted to see), and that the second does not do what you expect.

Good luck tweaking your solution... :-)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
