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: Accepted)

# 3  つの整数 A,B,C が与えられます。
# 整数 C が A 以上 かつ B 以下であるかを判定してください。

input = gets.chomp.split
a = input[0].to_i
b = input[1].to_i
c = input[2].to_i

if a <= c && c <= b
    puts "Yes"
else
    puts "No"
end
