C :

#include<stdio.h>
main()
{
	int x,y=0,z,t,count=0;
	scanf("%d",&x);
	while(x!=0)
	{
		count++;
		t=x%10;
		x/=10;
	    y=y*10+t;
	}
	printf("%d\n",count);
	z=y;
	while(y>=10)
	{
		printf("%d ",y%10);
		y/=10;
	}
	printf("%d\n%d\n",y%10,z);
}

C++ :

#include<bits/stdc++.h>
using namespace std;
string x;
int main()
{
	cin>>x;
	cout<<x.size()<<"\n";
	for(int i=0;i<x.size();i++)
	    cout<<x[i]<<" ";
	cout<<"\n";
	for(int i=x.size()-1;i>=0;i--)
	    cout<<x[i];
		
    return 0;
}
