( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Monks, please help. I need to find the unique number of values in a hash of hashes. For example, given the array below, I need to know how many kids are 12 years old.
%hoh = ( kevin => { age => "12", favorite_color => "blue", gender => "boy", }, john => { age => "11", favorite_color => "green", gender => "boy", }, lisa => { age => "11", favorite_color => "pink", gender => "girl", }, sara => { age => "13", favorite_color => "purple", gender => "girl", }, shelly => { age => "12", favorite_color => "purple", gender => "girl", }, );
How many kids are 12? In this case 2. Is there a quick way to get this number without looping through each hash and counting?

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
