题目大意 给你一个n 让你用0~n^2-1的数填满一个n*n的正方形 满足每个数值出现一次且每行每列的异或值相等 输出任意一种方案 分析 我们发现对于4*4的正方形 0  1  2  3 4  5  6  7 8  9 10 11 12 13 14 15 是满足条件的 那么如果对正方形中的每一个数都加上一个相同的数 那么这个正方形一定还是满足的 由于这种构造方式的异或值均是0 所以任意多个满足的正方形拼起来一定也是满足的 于是我们将正方形分为若干4*4的正方形 使得每一个正方形是一组连续的数 那…

题目 大意:构造一个n行n列的矩阵,使得每一行,每一列的异或和都相等,n是4的倍数. 先看4*4的矩阵,我们很容易构造出符合要求的矩阵,比如 0    1    2    3 4    5    6    7 8    9   10  11 12 13  14  15 这个矩阵每行每列的异或和都为0 对于一个n*n的矩阵,我们可以写成多个4*4的矩阵,为了保证数字不重复,可以对于其他的小矩阵都加上16,32等等 #include<iostream> #include<cstdio>…
