I turn in my java code in Code Jam but I get Run Time Error.
here my code
import java.util.*;
class Main
{
public static void main(String[] args) {
int t,i=0,k=0,count=0,v=0,c=0,n=0;
String r="\0";
int []st=new int[10],e=new int[10];
Scanner s = new Scanner(System.in);
t=s.nextInt();
for(i=0;i<t;i++)
{
n=s.nextInt();
for(k=0;k<n;k++)
{
st[k]=s.nextInt();
e[k]=s.nextInt();
}
for(k=0;k<n;k++)
{
if(k==0)
{
r='c'+r;
}
else if(k==1){
r=r+'j';
}
else if(k>1)
{
if(st[k]==e[k-1])
{
if(r.charAt(r.length() - 1) == 'j')
{
r=r+'j';
}
else if(r.charAt(r.length() - 1) == 'c')
{
r=r+'c';
}
}
else if(st[k]>e[v] || st[k]>e[k-1])
{
r=r+'c';
}
else if(st[v]<st[k] && st[k]<e[v])
{
c++;
break;
}else if(st[k]<st[v])
{
if(r.charAt(r.length() - 1) == 'j')
{
r=r+'c';
}
else if(r.charAt(r.length() - 1) == 'c')
{
r=r+'j';
}
}
}
}
if(c==0)
{
i++;
System.out.println("case #"+i+": "+r);
}
else if(c!=0)
{
i++;
c=0;
r="";
System.out.println("case #"+i+": IMPOSSIBLE");
}
if(i!=n){
--i;
}
r="";
}
}
}
Can anyone help me
thank You
