to traverse the tree in a spiral manner... 1. Insert the root into stack. 2. then in a loop check not both stack and queue are empty 3. { while(stack not empty) { node =pop(stack); cout<<node->info; insertintoqueue(node->left); insertintoqueue(node->right); }
while(queue not empty) { node = dequeue(queue); cout<<node->info; push(node->left); push(node->right); } } On Aug 22, 6:41 am, Aravind Prasad <raja....@gmail.com> wrote: > can anyone provide the correct and full logic for printing BST > spirally .. > > consider a tree > > a > / \ > b c > / \ / \ > d e f g > > output==>> abcgfeh > > here my doubt is ==>> > > how to find the level at wihich we are present (considering we are > using a stack for even levels and queue for odd levels) > > On Aug 21, 9:50 am, Stanley Cai <stanley.w....@gmail.com> wrote: > > > this one is not very right... > > > public void solution(String str) { > > > int t = Integer.parseInt(str, 2); > > > System.out.printf(Integer.toBinaryString((int)((1l<<32) - t))); > > > } > > > Still for this issue, it could be hard if the string is very long, length is > > more than 32 > > > On Fri, Aug 20, 2010 at 6:46 PM, GOBIND KUMAR <gobind....@gmail.com> wrote: > > > This is the code for question no-4 > > > > #include<iostream> > > > #include<conio.h> > > > using namespace std; > > > int main(){ > > > char str[20]; > > > char *sp=str; > > > int n=0; > > > int count=0;int carry=1; > > > gets(str); > > > //cout<<"\n"<<str<<"\n"; > > > while(*sp!='\0'){ > > > *sp=(*sp=='1')?'0':'1'; > > > sp++; > > > count++; > > > } > > > //cout<<"\n"<<str; > > > sp--; > > > if(*sp=='1'){ > > > *sp='0'; > > > carry=1; > > > } > > > else { > > > *sp='1'; > > > cout<<"\n"<<str; > > > getch(); > > > return 0; > > > } > > > sp--; > > > while(count && carry){ > > > if(*sp=='1'){ > > > *sp='0'; > > > carry=1; > > > } > > > else{ > > > *sp='1'; > > > carry=0; > > > } > > > sp--; > > > count--; > > > } > > > cout<<"\n"<<str; > > > getch(); > > > return 0; > > > > } > > > > -- > > > You received this message because you are subscribed to the Google Groups > > > "Algorithm Geeks" group. > > > To post to this group, send email to algoge...@googlegroups.com. > > > To unsubscribe from this group, send email to > > > algogeeks+unsubscr...@googlegroups.com<algogeeks%2bunsubscr...@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.
