@brijesh- itoa basically converts integer to string ..we are using the fact tht a number is multiple of 3 if its sum is multiple of 3 . we have int as string and we can traverse it ..for each character apply int sum+=*c-'0' (ankur missed the star :P) then on sum we use repeated subtraction...i hope its clear .
we are using all this just coz we have to use itoa ..otherwise there are more methods (check my frst post ) On Jul 30, 4:34 am, brijesh <brijeshupadhyay...@gmail.com> wrote: > @ankur I didnt get this... could u or anyone please elaborate! > > On Jul 30, 12:43 am, Ankur Khurana <ankur.kkhur...@gmail.com> wrote: > > > > > > > > > when you use itoa , what you get is a string. get the sum of all the digits > > , using c-'0' and then use repeated subtraction . . . > > > On Sat, Jul 30, 2011 at 1:01 AM, sukhmeet singh > > <sukhmeet2...@gmail.com>wrote: > > > > repeated subtraction !! > > > > On Sat, Jul 30, 2011 at 12:52 AM, nivedita arora < > > > vivaciousnived...@gmail.com> wrote: > > > >> Without using /,% and * operators. write a function to divide a number > > >> by 3. itoa() function is available. > > > >> all i cn thnk of is to use shift operator and addition , x/3=e^(logx- > > >> log3) or repetitive subtraction > > > >> but none of them uses itoa() ..ne idea how its done? > > >> thnks ! > > > >> -- > > >> You received this message because you are subscribed to the Google Groups > > >> "Algorithm Geeks" group. > > >> To post to this group, send email to algogeeks@googlegroups.com. > > >> To unsubscribe from this group, send email to > > >> algogeeks+unsubscr...@googlegroups.com. > > >> For more options, visit this group at > > >>http://groups.google.com/group/algogeeks?hl=en. > > > > -- > > > You received this message because you are subscribed to the Google Groups > > > "Algorithm Geeks" group. > > > To post to this group, send email to algogeeks@googlegroups.com. > > > To unsubscribe from this group, send email to > > > algogeeks+unsubscr...@googlegroups.com. > > > For more options, visit this group at > > >http://groups.google.com/group/algogeeks?hl=en. > > > -- > > Ankur Khurana > > Computer Science > > Netaji Subhas Institute Of Technology > > Delhi. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
