Solution in Ruby (2.3.3) (judge verdict: Runtime Error)


line = gets.chomp.split(' ').map { |e| e.to_i }
k = line[0]
s = line[1]

count = 0

for x in 0..k
(0..k).each do |x|
  (0..k).each do |y|
    (0..k).each do |z|
      if x + y + z == s
        count += 1
        break
      end
    end
  end
end

puts count
