C :

#include <stdio.h>
#include <string.h>
int main(){
  char a[10];
  int i,l;
  scanf("%s",a);
  l=strlen(a);
  printf("%d\n",l);
  for(i=0;i<l-1;i++)
  printf("%c ",a[i]);
  printf("%c\n",a[i]);
  for(i=l-1;i>=0;i--)
  printf("%c",a[i]);
  
  
  return 0;
}

C++ :

#include<iostream>
using namespace std;
int main(){
  string s;
  int a;
  cin>>s;
  a=s.length();
  cout<<a<<endl;
  for(int i=0;i<a-1;i++)
    cout<<s[i]<<" ";
  cout<<s[a-1]<<endl;
  for(int i=a-1;i>-1;i--)
    cout<<s[i];
  cout<<endl;
  return 0;
}

Java :

import java.util.Scanner;

public class Main{
   private static Scanner s = new Scanner(System.in) ;
   
   public static void main(String[] args) {
	  long num = s.nextLong() ;
	  
	  if(num<100000){
		  int a[] = get(num) ;
		  System.out.println(a.length);
		  for (int i = a.length-1; i >= 1; i--) {
			System.out.print(a[i]+" ");
		  }
		  System.out.println(a[0]) ;
		  for (int i = 0; i < a.length; i++) {
			 System.out.print(a[i]) ;
		  }
		  
	  }
   }
   
   public static int[] get(long num){
	   long temp = num ;
	   int n = 0 ;
	   while(temp>0){
		   temp/=10 ;
		   n++ ;
	   }
	   
	   int a[] = new int[n] ;
	   int i = 0 ;
	   while(num>0){
		   a[i] = (int) (num%10) ;
		   num/=10 ;
		   i++ ;
	   }
	   
	   
	   return a ;
	   
   }
}

Python :

a = raw_input()
l = len(a)
print(l)
for i in range(0, l - 1):
    print a[i],
print a[l - 1]
print a[::-1]
