Nowhere question mentions that the digits need to be non-repetitive. And in that case the answer to number of primes might also not be zero.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-35854287191991575592013-06-11T12:41:29.699+05:302013-06-11T12:41:29.699+05:30Tricky...
