slice function's documentation made user friendly

[aman-godara]

Previously, the documentation was bit lengthy and complex to understand especially for a person learning a programming language for the first time.
Although conceptually documentation is still same but it is simpler and shorter now.

Please let me know which one did you find easier to understand.

Thanks, looks good. I'd remove L207 (Deduction process:) and L212 (Extraction process:), I think they're redundant because the paragraphs that follow each already say what process is happening.

I added them so that a person can categorise a line under either of the 2 different processes. Explicitly grouping them makes it easier to get a bird view of the overall function and memorise what function does, otherwise there will be too many lines for a user under a single large umbrella to draw a map (in brain) of what function slice does. That was my reason to add these 2 lines, if others think the same then I will remove them.

Sounds good, I don't think it's too important to remove them.

Ok. 3 approvals, I will merge it. Thank you @aman-godara for this PR.
