C :

#include<stdio.h>
int main(){
int a,i=0,j,c[5];
scanf("%d",&a);
  while(a!=0){
    c[i++]=a%10;
    a=a/10;
  }
printf("%d\n",i);
for(j=i-1;j>0;j--)
  printf("%d ",c[j]);
printf("%d \n",c[j]);

for(j=0;j<i-1;j++)
  printf("%d ",c[j]);
printf("%d \n",c[j]);
  return 0;
}

C++ :

#include <stdio.h>
int main() {
	int v, i, digit;
	int d[10];
	scanf("%d", &v);
	digit = 0;
	while (v > 0) {
		digit++;
		d[digit] = v % 10;
		v /= 10;
	}
	printf("%d\n", digit);
	for (i = 1;i <= digit;i++)
		printf("%d ", d[digit + 1 - i]);
	printf("\n");
	for (i = 1;i <= digit;i++)
		printf("%d ", d[i]);
	printf("\n");
	return 0;
}

Pascal :

var 
  i,len:longint;
  s:string;

begin
  readln(s);
  len:=length(s);
  writeln(len);
  for i:=1 to len do
    write(s[i],' ');
  writeln;
  for i:=len downto 1 do
    write(s[i],' ');
  writeln;
end.

Java :

import java.util.Scanner;

class Main
{
	public void Work(int x)
	{
		int ct=0;
		int[] a=new int[5];
		while(x!=0)
		{
			a[ct++]=x%10;
			x=x/10;
		}
		System.out.println(ct);
		int i;
		for(i=ct-1;i>=0;i--)
		{
			System.out.print(a[i]+" ");
		}
		System.out.println();
		for(i=0;i<ct;i++)
		{
			System.out.print(a[i]+" ");
		}
		
		
	}
	public static void main(String[] args)
	{
		Scanner cin=new Scanner(System.in);
		Main t=new Main();
		while(cin.hasNext())
		{
			int x=cin.nextInt();
			t.Work(x);
		}
	}
}

Python :

x = list(raw_input())
print len(x)
print ' '.join(x),''
x.reverse()
print ' '.join(x),''
