Hi Keith,
I have disagree with the assessment that fine-tuning will result in a solution. The standard Sieve of Erathothenes approach is _not possible_ on standard computers due to the memory requirement estimate that eryksun has presented. The point of some of the problems on Project Euler is to create scenarios where you must be aware of what's computationally doable in a reasonable amount of resources. Problem 3 is precisely one of those situations where certain approaches will fail because those approaches don't respect physical reality enough. :P _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
