---------------------ruby code--------------------

after running ruby code

in below output at first occurrence of

can anyone explain how "nearValues"  is updating

(skip long useless code and output)

Well, your code says this:

    nearValues.size.times do |i|
      n = nearValues[i]
      next if $hash2[n].include?(pivot)
      nearValues[i] = nil

That means, er. .. If the pivot is in $hash2[n], whatever that means, 
then go to the next number. Otherwise, if the pivot is not in $hash2[n], 
nearValues[i] is set to nil.
This, incidentally, is absolutely terrible Ruby, and I want to inflict a 
lot of pain to the person who wrote it.

thank you for reply
can you please explain how nearValues is adding values

"sssssssssssssssssssssss"

"checkedValues"

["value6"]

"nearValues"

[nil]

"sssssssssssssssssssssss"

"checkedValues"

["value3"]

"nearValues"

[nil, "value6"]

"sssssssssssssssssssssss"

"checkedValues"

["value2"]

"nearValues"

[nil, "value3", "value6"]

"sssssssssssssssssssssss"

"checkedValues"

["value1"]

"nearValues"

[nil, "value2", "value3", "value4", "value5", "value6"]

"i"

No, because that's not in the code supplied. nearValues is passed to 
this method. The code is ugly but very readable. Go over it a few times 
and it will make sense.
Hints:
- "p" means "puts" and stands for 'send to the screen' (basically)
- Unknown methods can be looked up here: http://ruby-doc.org/core/
