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

#include<iostream>
using namespace std;
int main()
{
    int n1,n2,n3;
    cin>>n1>>n2>>n3;
    if(n3>n1&&n3<n2){
        cout<<"Yes"<<endl;
    }
    else if(n1==n2&&n1==n3){
        cout<<"Yes"<<endl;
    }
    else{
        cout<<"No"<<endl;
    }
    return 0;
