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

int cmpfunc(const void *a, const void *b){

    const char* aa = (const char*)a;
    const char* bb = (const char*)b;
    return strcmp(aa, bb);
}

int main(void){
    int a,b,c;
    scanf("%d %d %d",&a,&b,&c);
    if(c>=a && b>=c) printf("Yes\n");
    else printf("No\n");
    return 0;
