Little C loves number «3» very much. He loves all things about it.
Now he has a positive integer n. He wants to split n into 3 positive integers a,b,c, such that a+b+c=n and none of the 3 integers is a multiple of 3. Help him to find a solution.
Input
A single line containing one integer n (3≤n≤109) — the integer Little C has.
Output
Print 3 positive integers a,b,c in a single line, such that a+b+c=n and none of them is a multiple of 3.
It can be proved that there is at least one solution. If there are multiple solutions, print any of them.
