import java.util.*; 
public class SQ19
{ public static void main(String a[]) 
{ 
int i = 0, flag = 0; 
String s, tmp = ""; 
System.out.println("Enter the string"); 
Scanner sn = new Scanner(System.in); 
s = sn.nextLine().toUpperCase(); 
s = s + " "; 

while (i <= s.length() − 1) // from 0 till the character before the last position
{
if (s.charAt(i) != ' ')
{tmp = tmp + s.charAt(i);
if (s.charAt(i + 1) − s.charAt(i) == 1)
flag = 1;
}
else
{if (flag == 1)
System.out.println(tmp);
tmp = ""; flag = 0; // clear tmp and flag
}
i++; // loop variable
}
}}
