Ruby Numeric Reference Program

For myself I made a simple numerical reference program. Code below

qiita.rb

m = gets.chomp
n = gets.to_i


room = []

n.times do
  count = gets.chomp
  room.push(count)
end

a = 0
count = n

while n > 0

  if ! (room[a]).include?(m)
    puts room[a].to_i
  else
    count -= 1
    if count == 0
      puts "none"
    end
  end
  n = n - 1
  a = a + 1
end

First, enter the reference source value in the variable m. (Although it is character data) Based on that, we input numerical values and output only the numerical values that do not apply.

If all are not true, "none" is returned.

This if statement is a case that "does not apply", so I made it in the form of if !. Also, I thought that the character string could be referred to more easily with include? In the flow that first refers to a character string and converts it to a numerical value at the time of output just made it.
