Given an integer number, value, write a function that returns its multiplicative persistence.

multiplicativePersistence

int multiplicativePersistence(int value) {
  int counts = 0;
  int temp;
  while (value > 9) {
    temp = 1;
    while (value > 0) {
      temp *= value % 10;
      value = (value ~/ 10);
    }
    value = temp;
    counts++;
  }
  return counts;
}
