Starting with the code below, implement the sumDigits() function that calculates the sum of all the digits in an integer. You may assume that the inputs (x) will always be 0 or a positive integer.

void setup() {
  Serial.begin(9600);
  Serial.println(sumDigits(0));     // Should be 0
  Serial.println(sumDigits(2));     // Should be 2
  Serial.println(sumDigits(28));    // Should be 10
  Serial.println(sumDigits(504));   // Should be 9
  Serial.println(sumDigits(2048));  // Should be 14
  Serial.println(sumDigits(32767)); // Should be 25
}
 
void loop() {
  // Do nothing
}
 
int sumDigits(int x) {
  // YOUR CODE GOES HERE
}

Hints:

• You can assume that the maximum value on the input integer (x) is 32767
• You should not need to modify any other code outside the sumDigits() function

When you run the program, you should see the following output:
