Problem DescriptionHere are 10 little programs that are the solutions to the first ten even numbered programming challenges in Project Euler at MathsChallenge.net
Background & TechniquesMathschallenge.net is an educational math site run by British teacher Colin Hughes. He regularly posts math Jr. and Sr. level math problems and maintains an archive of past problems. Of interest to us is his Project Euler  a set of graded programming problems  current 21 problems arranged in 7 set of 3. It took me a few fun days solving all 21. Signup is required to participate and scores are posted under the userid you select. (I'm delphiforfun of course). At least two of the three problems at any level must be solved in order to gain access to the problems at the next level. Since it would not be fair to post all 21 here, I decided to post the even numbered problems to give viewers the flavor of the competition. These are "quick and dirty" programs  the kind you write when obtaining the answer is the primary motivation. Still there may be some techniques you can use in other places. I decided not to use any previously posted DF components or units, although the requirement to identify and use prime numbers, palindromes, permutations, and large integer arithmetic requires code which has already been posted elsewhere on DFF. Here you'll find the simplest versions of code to for these concepts. As usual, have fun! Running/Exploring the ProgramSuggestions for Further ExplorationsIf you like this kind of thing, for gosh sakes, sign up at ProjectEuler.net and challenge yourself. If you do sign up, use "delphi" somewhere in your handle so I can see how the "Delphians" are doing.
