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 <stdio.h>

int main(void){
	int A;
	int B;
	int C;
	
	char buf[3];
    fgets(buf,3,stdin);
    sscanf(buf,"%d %d %d",&A,&B,&C);
    
	while("%d > 100", A){
		"%d = %d-100",A,A;
	} 

	while("%d > 100", B){
		"%d = %d-100",B,B;
	} 

	while("%d > 100", C){
		"%d = %d-100",C,B;
	}
	
	if("%d >= %d",C,A){
		if("%d <= %d",C,B){
			printf("Yes");
		}else{
			printf("No");
		}
	}else{
		printf("No");
	}
