Solve in Python:
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 3 2

-----Sample Output-----
Yes

C=2 is not less than A=1 and not greater than B=3, and thus the output should be Yes.
S_list = list(map(int,input().split()))

if  S_list[1] - S_list[0] >= 0 and S_list[2]- S_list[0] >=0 and S_list[1] - S_list[2] >=0:
    result = "Yes"
else:
    result = "No"
print(result)
