Hi, As TC is over, so now I can submit the code of above prob:
import java.util.*; import java.util.regex.*; import java.text.*; import java.math.*; public class MathContest { public int countBlack(String ballSequence, int repetitions) { int sl = ballSequence.length(); int l = sl*repetitions; int a[] = new int[l]; for(int i=0;i<repetitions;i++) { for(int j=0;j<sl;j++) { if(ballSequence.charAt(j)=='W') a[j+i*sl]=0; else a[j+i*sl]=1; } } int count=0; int i=0; while(i<l-1) { if(a[i]==0) { for(int j=0;j<=(l-i-1)/2;j++) { int temp = a[j+i+1]; a[j+1+i]= a[l-1-j]; a[l-j-1] = temp; } } else { for(int j=i+1;j<l;j++) { if(a[j]==0) a[j]=1; else a[j]=0; } count++; } i++; } if(a[l-1]==1) count++; return count; } Thanks, Abhishek On Tue, Apr 26, 2011 at 11:03 PM, Arpit Sood <soodfi...@gmail.com> wrote: > @vaibhav he will be banned for sometime in topcoder if someone reports > about this, you can count on that..... > > > On Tue, Apr 26, 2011 at 10:42 PM, saurabh singh <saurab...@gmail.com>wrote: > >> >> Asking solution for a question 4m a live coding match is...... >> I am out of this topic.Apologies to anyone insulted 4m my side but i am >> firm on wat i said.Leave the decision on the conscience of other readers. >> >> On Tue, Apr 26, 2011 at 10:08 PM, vaibhav shukla <vaibhav200...@gmail.com >> > wrote: >> >>> I dont know y u ppl are so much concerned.He has just asked the >>> question.Did any one answered it ??No,then y r u taking pain. >>> and I dont know how is this a disgrace on spirit of coding ??Is asking >>> a question a disgrace ?rubbish. >>> >>> >>> On Tue, Apr 26, 2011 at 10:04 PM, radha krishnan < >>> radhakrishnance...@gmail.com> wrote: >>> >>>> May be he s innocent >>>> >>>> >>>> >>>> On Tue, Apr 26, 2011 at 10:02 PM, saurabh singh <saurab...@gmail.com>wrote: >>>> >>>>> And sincerely hope no one helps him in near future too.......... >>>>> >>>>> Disgrace on the spirit of coding >>>>> On Tue, Apr 26, 2011 at 9:38 PM, radha krishnan < >>>>> radhakrishnance...@gmail.com> wrote: >>>>> >>>>>> Are u mad man ? >>>>>> WTF ? >>>>>> wats ur TC handle ? >>>>>> >>>>>> >>>>>> >>>>>> On Tue, Apr 26, 2011 at 9:22 PM, Aakash Johari <aakashj....@gmail.com >>>>>> > wrote: >>>>>> >>>>>>> You can ask the solution after the contest. :) >>>>>>> >>>>>>> >>>>>>> On Tue, Apr 26, 2011 at 8:50 AM, Gunjan Sharma < >>>>>>> gunjan.khan...@gmail.com> wrote: >>>>>>> >>>>>>>> @Kamlesh: In this world this thing is termed as cheating.....
