Write a prgm to add sum of the digits of a number,then again sum that and print the output.
Example:
Sample input:9786456790
Sample output:7

• Program in JAVA :
  
  import java.io.*
  class solninjava // class name
  {
  public void main( ) throws IOException //function main used for input
  {
  BufferedReader std = new BufferedReader(new InputStreamReader(System.in)); //input from console
  System.out.print("Enter the Number : ");
  int n = Integer.parseInt(std.readLine());
  fun(n); // value n send to function fun
  }
  public void fun(int a) // function fun
  {
  int s=0; //to store sum of digit
  int d;
  while(a>0) // it runs till a>0
  {
  d=n%10;
  s=s+d;
  a=a/10;
  }
  if(s>10) // condition if sum is greater then 10
  {
  fun(s) //then that sum is again send to funtion fun as new number
  }
  else
  {
  System.out.println(" Output : "+s); //else print sum as output
  }
  }
  }
  
  Program in PYTHON 2.7.9
  """I have excuted the python program"""
  
  def fun(n):
  s=0
  while n>0:
  d=n%10
  s=s+d
  n=n/10
  
  if s>10:
  fun(s)
  else:
  print s
  
  no=integer(raw_input("Enter the number : "))
  fun(no)

• Python have different syntax as here curly bracket is presented by white space .... As white space are automatically removed in m4maths solution that why whitespace has been removed from python which plays important role ... If u know python then u know where u need to add white spaces ..... Java program do not need changes ... Logic is same for program in both

• In java program please correct one thing ...in function fun ...in while loop ....correct d = a%10 ...do like it thankx

• Logic :
  
  Result =number%9
  
  I have done this program in Python
  
  num=int(input())
  print(num%9)

• Sorry,I have done a mistake in previous solution.
  
  SOLUTION WITH CORRECT LOGIC
  num=int(input())
  if num > 0 and num % 9 ==0:
  print(9)
  else:
  print(num % 9)
  
  
  SAMPLE OUTPUT:
  INPUT:9999999999
  OUTPUT:9
  (In previous logic the output will be 0 which is wrong)

• It's not possible to get such a large value as an integer.
  so we should use some other data to get the input.
  
  
  import java.util.Scanner;
  import java.lang.String;
  
  public class MainClass {
  public static int digitSum(int num )
  {
  int sum=0;
  while(num>0)
  {
  sum+=num%10;
  num/=10;
  }
  return sum;
  }
  public static void main(String []args)
  {
  String num;
  Integer sum=0;
  Scanner sc=new Scanner(System.in);
  num=sc.next();
  for(int i=0;i
