How to determine if sum of any given consecutive array elements is equal to a given number in ruby?

I am attempting a coding problem which asks me to print "YES" if the sum of any consecutive array numbers is equal to the given number. The link to the challenge is here

my solution is here

b = Array.new
a = Array.new
t = gets.to_i
if t >= 0 && t <= 10
    t.times do
         n, x = gets.chomp.split.map(&:to_i)
         n.times do
         a << gets.to_i
         end
         (1..a.length).each do |num|
           a.each_cons(num).each do |pair|
            if  pair.inject(:+) == x
             b << "YES"
            else
             b << "NO"
            end
           end
         end
         if b.include?("YES")
             puts "YES"
        else
             puts "NO"
        end
     end
  end

Although they have accepted my answer, it does not pass all the test cases, hence I am not satisfied.Can someone help me with a correct, more efficient and elegant solution?
