i have solution with no extra space complexity but time complexity is >O(n)
traverse the list with a pointer ptr if odd no encounter then traverse the remaining list with tmp pointer with start point ptr->next and match the numbers with it....i hope it works :) On Sat, Jul 16, 2011 at 10:10 AM, shady <sinv...@gmail.com> wrote: > if hashing is allowed then it can be done in O(n)....... space complexity > in this case again will be O(n)........ this won't work for large numbers... > > > On Sat, Jul 16, 2011 at 1:58 AM, Nishant Mittal < > mittal.nishan...@gmail.com> wrote: > >> @sagar...
