public static int inc(int x){
int count=0;

while(x!=0){
x=x/10;
count++;
}
return  (count);
}

public static int jjj(int y){
int first=0,last=0;

last=y%10;
for(int i=0;i<inc(y);i++){
first=y/10;


}
return(Math.abs( first-last));
}
public static void main(String[] args) {
Scanner in = new Scanner( System.in);
int x;
System.out.println("Enter number");
x=in.nextInt();
System.out.println(jjj(x));
}
