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 Rust (1.15.1) (judge verdict: Accepted)

fn read() -> (i32, i32, i32) {
    let mut s = String::new();
    std::io::stdin().read_line(&mut s).unwrap();
    let vec: Vec<i32> = s
        .trim()
        .split_whitespace()
        .map(|x| x.parse().unwrap())
        .collect();
    (vec[0], vec[1], vec[2])
}

fn main() {
    let (a, b, c) = read();
    if a <= c && c <= b {
        println!("Yes");
    } else {
        println!("No");
    }
}
