System.out.println(getSmall(a));
}

private static String getSmall(Long input) {

if(input==1 || input==0)
return  input.toString();

int delim[] = {2, 3, 5, 7};
int delimIndex = 0;
Map<Integer, Integer> product = new TreeMap<Integer, Integer>();

int val = product.get(delim[delimIndex]);
product.put(delim[delimIndex], ++val);

}
}

for (Map.Entry<Integer, Integer> key : product.entrySet()) {
for (int i = 0; i < key.getValue(); i++) {
result.append(key.getKey());
}
}
return result.toString();

}
}
