You are given an integer input N and you have to find whether it is the sum or the difference of the integer 5. (5+5, 5+5+5, 5-5,5-5-5+5+5…..)

 

Example 1:

Input:
N = 10
Output:
YES
Explanation:
Because 10 can be 
written as a sum of 5+5.

 

 

Example 2:

Input:
N = 9
Output:
NO
Explanation:
9 can not be written
in the above form.

You don't need to read input or print anything. Your task is to complete the function isValid() which takes an integer N and returns "YES" or "NO".

 

Expected Time Complexity: O(1)
Expected Auxiliary Space: O(1)

 

Constraints:
-109<=N<=109
