Exposure to the @sandimetz.bsky.social 'Smalltalkism' (via her amazing POOD-I virtual course! 💜💚💙) inspired my monkey-patched quite n00bish and 'Shameless Green' answer to this week's @cassidoo.co interview question: BUT it is such a splendid thing to send messages to the objects!!! 🥰🙃😊
![```ruby
module ZoomifyArray
refine Array do
def zoom_in_by(factor)
raise ArgumentError, "Factor MUST be an Integer greater than or equal to 2!" unless factor.is_a?(Integer) && factor >= 2
number_of_rows = size
number_of_cols = first.size
bigger_grid = Array.new(number_of_rows * factor) { Array.new(number_of_cols * factor) }
each_with_index do |row, row_index|
row.each_with_index do |cell, col_index|
0.upto(factor - 1) do |shift_row_index|
0.upto(factor - 1) do |shift_col_index|
bigger_grid[(row_index * factor) + shift_row_index][(col_index * factor) + shift_col_index] = cell
end
end
end
end
bigger_grid
end
end
end

Recently, I discovered @cassidoo.co's colorful and beautifully handcrafted website and immediately subscribed to her insightful and funny weekly newsletter. As a bonus, there is an Interview QOTW inside each one, and this is my answer to the last one. More details: gist.github.com/izkreny/fae8...
![**Given an integer array and a number `n`, move all of the `n`s to the end of the array while maintaining the relative order of the non-`n`s.**
Bonus: do this without making a copy of the array!
Example:
```
$ moveNums([0,2,0,3,10], 0)
$ [2,3,10,0,0]
```
IMPORTANT: Ruby 3.4+ required because of default `it` block parameter!
Methods used:
* [Enumerable#partition](https://docs.ruby-lang.org/en/master/Enumerable.html#method-i-partition)
* [Array#flatten](https://docs.ruby-lang.org/en/master/Array.html#method-i-flatten)
```ruby
def move_numbers(integer_array, number) = integer_array.partition { it != number }.flatten
p move_numbers([ 0, 2, 0, 3, 10 ], 0) # => [2, 3, 10, 0, 0]
```
NO AI WAS USED IN THE CODING OF THIS SOLUTION! 🖖](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:hsxo3zhokwcxzilh4z3dyarj/bafkreiazaz2vnpbj2zojl6tig4twdibyab7ajgop5bpjbtl2w63taltzbu)
