    E. Easy Construction

    Problem Description

    Roundgod is given n,k, construct a permutation P of 1∼n satisfying that for all integers i in [1,n] , there exists a contiguous subarray in P of length i whose sum is k modulo n. If there are multiple solutions, print any of them. If there is no solution, print “-1” in one line.

    Input

    2 1

    Output

    1 2

    Note

    The sum of subintervals [1],[1,2] both satisfy ≡ 1(mod2), and their lengths are 1,2 respectively.

    Input

    3 1

    Output

    -1


    题目大意

    给定 n,k,问是否可以构造一个 1~n 的排列P,使得对于 1~n 中任意的数 i,P 都存在一个 长为 i 的连续子区间,使得区间和模 n 余 k。有解输出任意一组,无解输出 -1


    解题思路

    当 i = n 时,连续子区间是它本身,区间和为Sn,所以当有解的时候,Sn mod n = k
    因此 (( n*n+n )/ 2 ) mod n = k 成立是有解无解的分界线
    如果有解,那我们就分类构造子序列 ( n为偶数 ,n为奇数 )
    当n为偶数,可以推出 k=n / 2,我们先把n 和 k 直接构造出来,然后后面的用交叉构造的方式构造
    即子序列可以交叉构造为 {n, n/2, 1, n-1, 2, n-2, …}
    当n为奇数,可以推出 k = 0,我们就先把n构造出来,然后后面用交叉构造的方式构造即可,又由于此时 k = 0
    所以我们的子序列可以交叉构造为 {n, 1, n-1, 2, n-2, …}
    Ps:赛中有点迷,赛后看了出题人的讲解后才理解清楚透彻

    using namespace std;
    int main()
    {
    	ios::sync_with_stdio(false),cin.tie(nullptr),cout.tie(nullptr);

    	cin>>n>>k;
    	int ret = ((n*n+n)/2)%n;//P of length i whose sum is k modulo n --> Sn % n = k
    	if(ret != k)
    	{	
    		cout<<"-1";
    	}else
    	{
    		if(n % 2 == 0)
    		{
    			//如果n是偶数,可知k=n/2,则 {n, n/2, 1, n-1, 2, n-2, ...} 	
    			cout<<n<<" "<<n/2<<" ";

    Road Construction
    Time Limit: 2000MS Memory Limit: 65536K
    Total Submissions: 14363 Accepted: 7228
    Description

    It’s almost summer time, and that means that it’s almost summer construction time! This year, the good people who are in charge of the roads on the tropical island paradise of Remote Island would like to repair and upgrade the various roads that lead between the various tourist attractions on the island.

    The roads themselves are also rather interesting. Due to the strange customs of the island, the roads are arranged so that they never meet at intersections, but rather pass over or under each other using bridges and tunnels. In this way, each road runs between two specific tourist attractions, so that the tourists do not become irreparably lost.

    Unfortunately, given the nature of the repairs and upgrades needed on each road, when the construction company works on a particular road, it is unusable in either direction. This could cause a problem if it becomes impossible to travel between two tourist attractions, even if the construction company works on only one road at any particular time.

    So, the Road Department of Remote Island has decided to call upon your consulting services to help remedy this problem. It has been decided that new roads will have to be built between the various attractions in such a way that in the final configuration, if any one road is undergoing construction, it would still be possible to travel between any two tourist attractions using the remaining roads. Your task is to find the minimum number of new roads necessary.

    Input

    The first line of input will consist of positive integers n and r, separated by a space, where 3 ≤ n ≤ 1000 is the number of tourist attractions on the island, and 2 ≤ r ≤ 1000 is the number of roads. The tourist attractions are conveniently labelled from 1 to n. Each of the following r lines will consist of two integers, v and w, separated by a space, indicating that a road exists between the attractions labelled v and w. Note that you may travel in either direction down each road, and any pair of tourist attractions will have at most one road directly between them. Also, you are assured that in the current configuration, it is possible to travel between any two tourist attractions.

    Output

    One line, consisting of an integer, which gives the minimum number of roads that we need to add.
