In practice, any coin issuing entity will make coins in such a way that a greedy algorithm is optimal. That is, noone is issuing coins as 7c, 6c and 1c coins (a case where greedy isn't optimal to make 24c change (greedy gives you 3 x 7c + 3 x 1c, while optimal is 4 x 6c)). Instead typical coin denominations are 1c, (2c), 5c, 10c, 20 or 25c, (50c), 100c, (200 or 250c), (500c). For instance, US dollar coins come in 1c, 5c, 10c, 25c, 50c, and 100c; Euro coins in 1c, 2c, 5c, 10c, 20c, 50c, 100c, and 200c; Yen coins in 1y, 5y, 10y, 50y, 100y, 500y; Pound Sterling coins in 1p, 2p, 5p, 10p, 20p, 50p, 100p, 200p (effectively the same as Euro coins). For all, a greedy algorithm is optimal.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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.
