Constraints

-100≤A,B,C≤100

A, B and C are all integers.

Input

A B C

Output

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

Sample Input 1

1 3 2

#!/usr/bin/env php
<?php
if (basename(__FILE__) == basename($_SERVER['PHP_SELF'])) {

	$a = 0;
	$b = 0;
	$c = 0;

  while ($line = fgets(STDIN)) {
    $tokens = explode(' ', $line);
    $a = intval($tokens[0]);
    $b = intval($tokens[1]);
    $c = intval($tokens[2]);
  }

  if ($a <= $c && $c <= $b) {
  	echo("Yes");
  } else {
  	echo("No");
