input: Write a function to evaluate and compare the performance of two different heuristics algorithms. The function should take in two data sets and return a string indicating which algorithm is faster, or if they have the same performance time. If both data sets are None, return "No data provided for comparison".
  assert compare_heuristics(None, None)=="No data provided for comparison"
  assert compare_heuristic(data1, data2)=="Algorithm 1 is faster than algorithm 2"
  assert compare_heuristic(data3, data4)=="Algorithm 2 is faster than algorithm 1"
  assert compare_heuristic(data5, data6)=="Both algorithms have the same performance time"
output: def compare_heuristics(data1, data2):
      if data1 is None and data2 is None:
          return "No data provided for comparison"
      time1 = sum(data1) if data1 else 0
      time2 = sum(data2) if data2 else 0
      if time1 < time2:
          return "Algorithm 1 is faster than algorithm 2"
      elif time1 > time2:
          return "Algorithm 2 is faster than algorithm 1"
      else:
          return "Both algorithms have the same performance time"
