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++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <iostream>
using namespace std;

int main() {

	int n1 = 0,n2 = 0,n3= 0;
	cin >> n1 >> n2 >> n3;

	if(n3 > n1 && n3 < n2){
		cout << "Yes";
	}else{
		cout << "No";
	}

	
	// your code goes here
	return 0;
