s
doesn’t seem to be being read in correctly: it might be the same problem as in C++, where after you read in t
, the value of sc.nextLine()
will just be the rest of the line containing t
i.e. the empty string.
I don’t know enough about Java’s IO to be sure, though.
Edit:
This seems to work:
/* package codechef; // don't place package name! */
import java.util.*;
import java.lang.*;
import java.io.*;
/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner sc = new Scanner(System.in);
int t= sc.nextInt();
sc.nextLine(); // Skip the remainder of the line containing T.
for(int i=0 ; i<t ;i++ )
{
String s = sc.nextLine();
boolean b=false;
int n= s.length();
if(n>3)
{
b= ( s.charAt(0) == '<' && s.charAt(1) == '/' && s.charAt(n-1) == '>' );
for( int j=2 ; j< n-1 ;j++)
{
if(!(Character.isLowerCase(s.charAt(j)) || Character.isDigit(s.charAt(j))))
b=false;
}
}
if(b)
System.out.println("Success");
else
System.out.println("ERROR");
}
sc.close();
}
}
Or maybe, the logic was incorrect here.
He wrote
for(int j = 0; j < n - 1; j++)
instead.
And btw, instead of nextLine()
, he can use the next()
method of Scanner Class everywhere.
Or both
