Automatic Syncing of Google contacts with iCloud contacts

Hi everyone, I am using Google contacts since long. I have recently switched to iPhone. I have set up my Google contacts to work with iPhone. Meanwhile, I wanted to use iCloud contacts as well so I have imported all Google contacts there. But I want to maintain Google contacts as well. Is there any way, both the contact lists automatically sync with each other? If I add or edit any contact in any of the contact list, the change is automatically updated into other list…… Regards
