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

a,b,c = gets.chomp.split(' ').map{|n| n.to_i}

if c >= (a + b)/2
  for i in a..b do
    puts i
  end
  exit
end

result = []
n = c - 1
for i in 0..n do
  result.push a + i
  result.push b - i
end
result.sort!
for hoge in result do
  puts hoge
end
