Posted by Ravi Maggon 21 Aug 2010 19:08
Tried all test cases i know but it gives wrong answer for test#1.
Can anyone please tell me what case is failing in my code?

#include<stdio.h>
int count=0,ni;
int seq[31][31];
int a=-1,b=-1,c=-1,move=-1,movea=-1,moveb=-1,movec=-1,flag=0,go=0;
void tower(int n,char beg,char aux,char end)
{
if(n==1)
{
int begin,ends,k,m;
begin=(int)(beg-48)-1;
ends=(int)(end-48)-1;
count++;
for(k=ni-1;k>0;k--)
seq[ends][k]=seq[ends][k-1];
seq[ends][0]=seq[begin][0];
for(k=0;k<ni-1;k++)
seq[begin][k]=seq[begin][k+1];
seq[begin][ni-1]=0;
/*for(k=0;k<3;k++)
{
for(m=0;m<ni;m++)
printf("%d",seq[k][m]);
printf("\n");
}
printf("\n");
*/for(k=0;k<ni;k++)
{
if(seq[a][k]==1)
{
movea=1;
break;
}
}

return;
