Answer 1

ANSWER
........................



{


                static void teja(int num)


{         


int m = num;

int dig;


int c;


int d=0;

int n = num;

int dig2;

int a = 0;

for(int i = 0;i<=9;i++)


{


m=num;



c=0;


while(m>0)


{


dig=m%10;


if(dig==i)


c++;


m/=10;
}
if(c==1)
d++;
}


while(n>0)


{
dig2 = n%10;


a++;


n/=10;



}
if(a==d)


System.out.println(num+” is a Unique Number “);
else
System.out.println(num+” is not a Unique Number “);
}
}

Answer 2

import java.util.*;

class unique_number

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter a number to check whether it is unique number or not");

int n=sc.nextInt();

int cpy=n;

int d=0;

int c=0;

int flag=0;

for(int i=0;i<=9;i++)

{

n=cpy;

c=0;

while(n>0)

{

d=n%10;                

if(d==i)

{

   c++;

}

n=n/10;

}

if(c>1)

{

flag=1;

break;

}

}

if(flag==0)

{

System.out.println("Unique number");

}

else

{

System.out.println("Not a unique number");

}

}

}
