standard outputLittle 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 $$$n$$$ ($$$3 \leq n \leq 10^9$$$) — 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.
