the first statement takes the elements from the array @keys, increments them and adds to the hash %hash.
first point is, you only have letters, no numbers, so Perl won't "increment" them, and will just add them as they already are to the hash.
secont point, the hash takes two elements to populate a key-value pair. for example, a hash %h = (a => 1, b => 2, c => 3) could also be written as %h = qw{a 1 b 2 c 3}.
the second statement takes each element from the array as a key of the hash, incrementing its value each time it's processed (which means if you have twice the element "a" in the array, the value of the key "a" in the hash will be 2 etc). if you want to use map to do that, it'd like map { $hash{$_}++ } @keys.

to format your post; it's "PerlMonks-approved HTML":

  • 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.
