Consider rewriting learnshell.org Array-Comparison

[shaun-chiang]

• The prior tutorial, Arrays, already conveys the same information: how to access array indexes, evaluate number of elements in array
• Exercise incorporates many (at this point) unlearned operations: for, if, array assignment (the next tutorial is only "Basic Operations")

I'm leaving this as an issue (instead of a PR) as I'm not familiar as to the original reasoning of this page, and it's order in the list of tutorials.

@bashedpotato, please look into this

I believe that this added chapter, which was added Jun14 2018 ( #310) right after the basic Arrays chapter, is indeed

1. too complicated to its position
2. includes just the info already present in the basic Arrays chapter,

Therefore i would recommend to either:

1. hide it
   -or-
2. move it anywhere to the shell "Advanced Tutorials" section
