Question:-

Write a program to accept a number and check whether it is unique or not.

A number is said to be a unique number if it's digit are not repeated.

This is the program.

public class Unique_number

{

public static void main(String args[])

{

int n;int flag=1;

Scanner in=new Scanner(System.in);

System.out.println("Enter a number: ");

n=in.nextInt();

int c;

int no=n, x=n;

while(n!=0)

{

int d=n%10;

no=x;

while(no!=0)

{

int r=no%10;

if(r==d)

c++;

no/=10;

}

}

if(c==1)

System.out.println("It is a Unique number");

else

System.out.println("It is not a Unique number");

}

}
