Change the name of the file to TASK(no. of the task)_(your initials).

[omkarghugarkar007]

Yes, I have changed the names now. Thanks!

Hey, do not commit your .ipynb checkpoints or changes to other files that do not involve your task done. Just take a look at the files changed once. Rest looks good!

[omkarghugarkar007]

Yeah done, I deleted the checkpoints. Rest files are good, only 2 tasks which I have completed, those files are changed. Thanks!

[omkarghugarkar007]

Is there any further change required and then it will be merged?
