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<bits/stdc++.h>
#include<algorithm>
#define ll long long
#define fast_io ios_base::sync_with_stdio(false);cin.tie(NULL);cout.tie(NULL);

using namespace std;
int main()

    fast_io
    ll t,i,j,n,a,b,c,sum=0;
    cin>>a>>b>>c;
    if(c>=a&&c<=b)
        cout<<"Yes"<<endl;
    else
        cout<<"No"<<endl;

    return 0;
