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 Haskell (GHC 7.10.3) (judge verdict: Accepted)

import Control.Monad
import qualified Data.ByteString.Char8 as BS
import Data.Maybe (fromJust)
import Data.List as List

solve :: Int -> Int -> Int -> String
solve a b c
    | c >= a && c <= b = "Yes"
    | otherwise = "No"
    

main :: IO()
main = do
    [a, b, c] <- map (fst . fromJust . BS.readInt) . BS.words <$> BS.getLine
    putStrLn $ solve a b c
