input: Write a function that takes in a dictionary (string → integer) and returns the sum of all values in the dictionary. Assertions that test the function should be provided.
  
  ### Function:
  def compute_dict_sum(input_dict):
      result = 0
      for val in input_dict.values():
          result += val
      return result
  
  ### Assertions:
  assert compute_dict_sum({"a": 5, "b": 10, "c": 15}) == 30
  assert compute_dict_sum({"x": 2, "y": 4, "z": 6}) == 12
  assert compute_dict_sum({}) == 0
  assert compute_dict_sum({"one": 1, "two": 2, "three": 3}) == 6
output: def compute_dict_sum(input_dict):
      result = 0
      for val in input_dict.values():
          result += val
      return result
