@suhas22 Please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```

Copy and paste these if you can’t find the correct symbol on your keyboard.

I’d also suggest that you either provide the information that was requested when you created this topic, or copy/paste the information that you see in your serial monitor when you reboot your ESP8266 - use triple backticks at the beginning and end of this data also.
