The shortest j solution to solve a contest problem "How many radians per hour does a minute hand travel?"
Another problem used PrimePi _1&p: . The values were out of range for j7 but were accessible with wolfram alpha. Perhaps they counted zeros or used a series approximation? This is an opportunity for algorithmic enhancement. Approximations: http://www.primefan.ru/stuff/primes/table.html Solution: http://www.wolframalpha.com/input/?i=PrimePi[10000000000] limit error: _1 p: 10000000000 |limit error | _1 p:10000000000 5 days remain in this contest! http://www.athena.kurukshetra.org.in/ ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
