Representar K^N como la suma de exactamente N números

Dados dos números N y K , la tarea es representar K ^N como la suma de exactamente N números. Escriba NA si tales números no son posibles.
Ejemplos: 
 

Entrada: N = 5, K = 2 
Salida: 2 2 4 8 16 
Explicación: 
2 + 2 + 4 + 8 + 16 = 32 = 2 ⁵
Entrada: N = 4, K = 3 
Salida: 3 6 18 54 
Explicación: 
3 + 6 + 18 + 54 = 81 = 3 ⁴ 
 

Planteamiento: Para obtener números tales que su suma sea una potencia de K, podemos elegir los números que cumplen la condición: 
 

Esto siempre dará la suma como una potencia de K. 
Por ejemplo: Esto se puede ilustrar como: 
 

Let N = 3 and K = 4.

We need to represent 43 (=64)
as the sum of exactly 3 numbers

According to the mentioned approach,
The 3 numbers which can be chosen are 
  (41) = 4
  (42 - 41) = 16 - 4 = 12
  (43 - 42) = 64 - 16 = 48

Adding the numbers = 4 + 12 + 48 = 64
which is clearly 43

Therefore the required 3 numbers
are 4, 12 and 48.
