Little C loves number «3» very much. He loves all things about it.
Now he has a positive integer nn. He wants to split nn into 33 positive integers a,b,ca,b,c, such that a+b+c=na+b+c=n and none of the 33 integers is a multiple of 33. Help him to find a solution.
Input
A single line containing one integer nn (3≤n≤1093≤n≤109) — the integer Little C has.
Output
Print 33 positive integers a,b,ca,b,c in a single line, such that a+b+c=na+b+c=n and none of them is a multiple of 33.
It can be proved that there is at least one solution. If there are multiple solutions, print any of them.

题意:给你一个n,把n分解成三个数都不是3的倍数的数。
题解:数论 总共三种情况,余0,1,2的情况。分类处理。
c++:
#include<bits/stdc++.h>
using namespace std;
int main()
{
int n;
cin>>n;
if(n%3==2) printf("2 2 %d\n",n-4);
else printf("1 1 %d\n",n-2);
return 0;
}
python:
n=int(input())
if n%3==2:print("2 2 %d"%(n-4))
else:print("1 1 %d"%(n-2))
