Thank you for the PR, unfortunately this doesn't bind to our conversation while assigning the issue, kindly follow that, that is the acceptance criteria for this issue.
For ref: #66 (comment)

FYI: reason because of which the build is failing

[vivek6201]

@krishnaacharyaa hey all checks have been passed, please check the code as i have the addressed the suggestions given in the comment of issue #73

[krishnaacharyaa]

@vivek6201, there seems to be some communication gap,

Sure @vivek6201, It's almost done in #73, just try to resolve the comments, that would suffice.

As mentioned here, the task is to simply complete #73 (comment), and the rest of the implementation to be followed from #73,
(It is linked to another story, and then we had aggreed upon the implementation, so kindly follow the same approach)

hey @krishnaacharyaa , changes have been made according to comments please check

[krishnaacharyaa]

Kindly follow the comment highlighted more than twice for now, take your time understand what is the requirement and come up with a solution, too much time is exhausted mutually explaining thing recursively.

[krishnaacharyaa]

You should just solve the comment #73, nothing plus nor minus, you tried doing everything except the thing requested...

Just implement #73 (comment)

[vivek6201]

[krishnaacharyaa]

Thank you for the quick fix, looks good now, merging this.

p.s: kindly take care of the commit messages next time, the commit messages helps in the nice structuring of the code
