Consider the following method which is intended to create an array which stores each decimal digit of the positive int num in ascending order of value.

/** @param num a positive integer * @return an array containing each digit of num, with the units * digit at index 0 and higher place value digits at higher indices. */

public int[] digits(int num) { 

int length = 0; int pv = 1; while (num >= pv)

{

length += 1;

pv *= 10;

}

int[] dig = new int[length]; for (int k = 0; k < length; k++)

{

 /* missing code */ } 

return dig;

}

• dig[k]=num/10; num = num % 10;

• dig[k]=num%10; num = num % 10;

• dig[k]=num%10; num /= 10;

• dig[k]=num/10; num /= 10;

• dig[k]=num%10; num *= 10;
