group by property

[bhojendra]

Thanks. It is grouping as expected. But it is returning empty [].

[
  {
    "g": [],
    "b": []
  },
  {
    "g": [],
    "b": []
  },
  ...
]

Probably this line is issue:

NewList[Dict['n'] - 1][Dict['m'][0]].append(Dict)

You are probably decreasing n value. I have random number rather than increasing number. So, I have to match the n exactly not by decreasing.
