New Year Chaos, I don't know why it fails at case: `1 2 5 3 7 8 6 4` ?

test.rb

#!/bin/ruby

require 'json'
require 'stringio'

# Complete the minimumBribes function below.
def minimumBribes(q)

too = false
bs = 0

(1..q.count).each do |i|
 a = q[i-1]
 brides = a - i
 #p "#{a} at #{i} is #{brides}"
 if brides > 2 
  bs = 0 
  puts "Too chaotic"
  break
  else
  bs = bs + brides if brides > 0
 end
end

puts (bs) if bs > 0


end

t = gets.to_i

t.times do |t_itr|
    n = gets.to_i

    q = gets.rstrip.split(' ').map(&:to_i)

    minimumBribes q
end
