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 Scala (2.11.7) (judge verdict: Runtime Error)

object Main extends App {
  val scan = new java.util.Scanner(System.in)
  val ns: Array[Long] = Array.fill(1e5.toInt + 100)(0l)
  val n, k = scan.next().toInt
  for (_ <- 1 to n) yield ns(scan.next().toInt) += scan.next().toInt
  val acc = ns.scanLeft(0l)((s, n) => s + n).drop(1)
  println((0 to ns.length).zip(acc).dropWhile(_._2 < k).head._1)
}
