input: Write a python function to find the sum of the 10 smallest even numbers larger than a given number.
  assert sum_even_numbers(5) == 110
  assert sum_even_numbers(20) == 330
  assert sum_even_numbers(0) == 110
output: def sum_even_numbers(n):
      even_numbers = []
      current = n + 1 if n % 2 == 0 else n + 2
      while len(even_numbers) < 10:
          even_numbers.append(current)
          current += 2
      return sum(even_numbers)
