Problem:
Score : 200 points

Problem Statement

Rng is preparing a problem set for a qualification round of CODEFESTIVAL.

He has N candidates of problems. The difficulty of the i-th candidate is D_i.

There must be M problems in the problem set, and the difficulty of the i-th problem must be T_i. Here, one candidate of a problem cannot be used as multiple problems.

Determine whether Rng can complete the problem set without creating new candidates of problems.

Constraints

1 \leq N \leq 200,000

1 \leq D_i \leq 10^9

1 \leq M \leq 200,000

1 \leq T_i \leq 10^9

All numbers in the input are integers.

Partial Score

100 points will be awarded for passing the test set satisfying N \leq 100 and M \leq 100.

Input

Input is given from Standard Input in the following format:

N
D_1 D_2 ... D_N
M
T_1 T_2 ... T_M

Output

Print YES if Rng can complete the problem set without creating new candidates of problems; print NO if he cannot.

Solution in Ruby (2.3.3) (judge verdict: Wrong Answer)

N = gets.chop.to_i;
D = gets.chop.split.map(&:to_i)
M = gets.chop.to_i;
T = gets.chop.split.map(&:to_i)

if M > N
  puts "No"
  exit
end

h = Hash.new

for i in D
  if h.has_key?(i)
    h.store(i, h.fetch(i) + 1)
  else
    h.store(i, 1)
  end
end

for i in T
  if h.has_key?(i) == false
    puts "NO"
    exit
  else
    if h.fetch(i) == 0
      puts "NO"
      exit
    else
      h.store(i, h.fetch(i) - 1)
    end
  end
end

puts "YES"
