题目链接: http://codeforces.com/problemset/problem/710/C 题目大意: 构造一个N*N的幻方.任意可行解. 幻方就是每一行,每一列,两条对角线的和都相等. 题目思路: [模拟] 分为奇幻方.单偶幻方和双偶幻方三种构造. 具体分类可以查看百度.幻方的N种构造方法 // //by coolxxx //#include<bits/stdc++.h> #include<iostream> #include<algorithm> #i…

构造. 先只考虑用$0$和$1$构造矩阵. $n=1$,$\left[ 1 \right]$. $n=3$,(在$n=1$的基础上,最外一圈依次标上$0$,$1$,$0$,$1$......) $\left[ {\begin{array}{*{20}{c}}0&1&0\\1&1&1\\0&1&0\end{array}} \right]$. $n=5$,(在$n=3$的基础上,最外一圈依次标上$1$,$0$,$1$,$0$......) $\left[ {\b…

1 奇数阶幻方构造法 (1) 将1放在第一行中间一列; (2) 从2开始直到n×n止各数依次按下列规则存放:按 45°方向行走,向右上,即每一个数存放的行比前一个数的行数减1,列数加1 (3) 如果行列范围超出矩阵范围,则回绕.例如1在第1行,则2应放在最下一行,列数同样加1; (4) 如果按上面规则确定的位置上已有数,或上一个数是第1行第n列时,则把下一个数放在上一个数的下面. #include<iostream> #include<algorithm> #include<…

Content 构造出一个 \(n\times n\) 的矩阵,使得这个矩阵由 \(1\sim n^2\) 这些数字组成,并且这个矩阵的每行,每列,以及对角线的和都为奇数. 数据范围:\(1\leqslant n\leqslant 49\).\(n\) 为奇数. Solution 这题其实就是 \(\texttt{NOIP2015}\) 提高组的 \(\texttt{D1T1}\),因为--都是奇数幻方,都是要求每行,每列,以及对角线的和都相等.只不过这道题目要求和都为奇数罢了. 但是,只要你利…
