Line 1,826:
guessing 29 too low
guessing 30 found the number in 7 turns.</pre>
Since Ruby 2.0 it can be done actually using a binary search (output as above):
<lang ruby>r = (1..100)
secret = rand(r)
turns = 0
puts "Guess a number between #{r.min} ans #{r.max}"
r.bsearch do |guess| # bsearch works on ranges
turns += 1
low_high = secret <=> guess # -1, 0, or 1
msg = ["found the number in #{turns} turns","too low", "too high"][low_high]
puts "Guessing #{guess} \t #{msg}"
low_high
end
