Answer 1

import java.util.*;
public class SumLargeSmall
{
public static void main(String args[])
{
  Scanner sc=new Scanner(System.in);
  System.out.println("Enter number :");
  int d,ld=0,sd=0,num;
  num=sc.nextlnt();
  ld=num%10;
  sd=num%10;
  while (num>0)
  {
    d=num%10;
    if(d>ld)
      ld=d;
    if(d<sd)
      sd=d;
num/=10;
}
System.out.println("Largest digit :"+ld);
System.out.println("Smallest digit :"+sd);
if ((sd+ld)%2=0)
   System.out.println("Sum of largest and smallest
   digts is even");
else
System.out.println("Sum of largest and smallest
digts is odd");
 }
}
