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 C++ (GCC 9.2.1) (judge verdict: Accepted)

#include <bits/stdc++.h>
using namespace std;
int main(void){

    int a, b, c;
    cin >> a >> b >> c ;
    
    //*
    if(a <= c && b >= c){
        cout << "Yes" << endl;
    } else {
        cout << "No" << endl;
    }
    //*/
    
    //cout << a.at(0) - 'a' + 'A' << b.at(0) - 'a' + 'A' << c.at(0) - 'a' + 'A' << endl;

    return 0; 
}
