What's New - April, 2009

April 4, 2009: While the design of the bookmark might be perfect, there was room to improve the implementation. Perfect Bookmark V4 was posted today with a few image and font handling enhancements.
April 6, 2009: Brute Force is one of my favorite programs on the site. It can solve a wide range of puzzles/problems which have a restricted range of integer solutions. Give the program the possible variable values and the equations describing the conditions to be met, and the program does an exhaustive search for sets of values satisfying the conditions. The download files include 24 sample problems. Brute Force Version 2.3 posted today allows problems with fewer variable values than variables to be solved. The newly included "Binary Conversion" sample problem finds numbers between 6 and 16 with the two middle digits in the binary representation having the same value.

Concentration is the card
game requiring that pairs of face-down cards be drawn and replaced until a match
is made. In case that game is too easy,
Concentration Version 2 adds the option
of requiring sets of three matching cards be found before they are removed.
April 22, 2009: It has been a while since we have had a beginners program posted, so here is one that some might have fun with. Number Words converts any input integer between 0 and a million to words. So 456,789 as input for example, displays the result "Four hundred fifty-six thousand seven hundred eighty-nine". About 60 lines of user written code do the job.
