vector 解决约瑟夫环问题

总共 n个人 从s号开始，m个删去一个

#include<iostream>
#include<vector>
using namespace std;
int main()
{
	vector<int>v;
	int n, s, m;
	cin >> n >> s >> m;
	for (int i = 1; i <= n; i++)
	{
		v.push_back(i);
	}
	auto it = v.begin() + s-1;
	while(v.size()-1)
	{
		for (int j = 0; j < m-1; j++)
		{
			it++;
			if (it == v.end())
				it = v.begin();
		}
		cout << *it << " ";
		it = v.erase(it);
		if (it == v.end())
			it = v.begin();
	}

}
