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.chop.split.map(&:to_i)
ab = Array.new(N+1, [0, 0])
(1..N).to_a.each do |i|
  ab[i] = gets.chop.split.map(&:to_i)
end

ab.sort! do |a, b|
  a[0] <=> b[0]
end

result = (1..N).to_a.each do |i|
  @K -= ab[i][1]
  break ab[i][0] if @K <= 0
end

puts result
