Problem Statement

You are given three integers A, B and C.
Determine whether C is not less than A and not greater than B.

Constraints

-100≤A,B,C≤100

A, B and C are all integers.

Input

Input is given from Standard Input in the following format:

A B C

Output

If the condition is satisfied, print Yes; otherwise, print No.

Sample Input 1

1 3 2

Sample Output 1

Yes

C=2 is not less than A=1 and not greater than B=3, and thus the output should be Yes.

Sample Input 2

6 5 4

Sample Output 2

No

C=4 is less than A=6, and thus the output should be No.

Sample Input 3

2 2 2

Sample Output 3

Yes

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

N, K = gets.split.map(&:to_i)
result = []

N.times do
  a, b = gets.split.map(&:to_i)

  if result[K - 1].nil?
    if (K - result.length) < b
      result.push(*[a] * (K - result.length))
    else
      result.push(*[a] * b)
    end
  elsif a < result[K - 1]
    less_idx = result.rindex { |n| n <= a }
    result.insert(less_idx + 1, *[a] * (K - (rindex + 1)))
  end
end

puts result[K - 1]
