Yes, as an afterthought it would have been better to build two arrays
for example (1..5000).to_a and (3000..8000).to_a and randomize them.

I totally brainfarted !!! The reviewed version, with surprising
results, at least for me: Set#- is less efficient than Array#- (unless
I'm doing something wrong again):
require 'benchmark'
require 'set'
n = 1_000
a1 = (1..5_000).sort_by { rand }
a2 = (3_000..8_000).sort_by { rand }
s1 = a1.to_set
s2 = a2.to_set
Benchmark.bmbm do |x|
x.report("array minus") do
n.times {a1 - a2}
end
x.report("set minus") do
n.times {s1 - s2}
end
end
$ ruby set_bm.rb
Rehearsal -----------------------------------------------
array minus 1.370000 0.010000 1.380000 ( 1.398643)
set minus 10.880000 3.060000 13.940000 ( 14.100127)
------------------------------------- total: 15.320000sec
user system total real
array minus 1.410000 0.010000 1.420000 ( 1.428664)
set minus 10.990000 3.070000 14.060000 ( 14.188415)
Could it be because Array is written in C, while Set is in Ruby
iterating over an Enumerable object? Did I do something wrong again?
Jesus.
