input = new Scanner(System.in);
public static void main(String[] args)
{
int number=0;
int nuberof1=0;
char ch=' ';
String
arrayofNumber="";
System.out.print("Enter the value of n:
");
number=input.nextInt();
for(int
i=1;i<=number;i++){
arrayofNumber+=i;
}
for(int
i=0;i<arrayofNumber.length();i++){
if(arrayofNumber.charAt(i)=='1'){
nuberof1+=1;
}
}
System.out.print("Total
Occurrence of 1: "+nuberof1+"\n");
System.out.print("Try again
Y/N?");
ch=input.next().charAt(0);
if(ch=='Y' || ch=='y'
){
main(args);
}else{
System.exit(0);
