此处有目录↑描述在成功地发明了魔方之后,鲁比克先生发明了它的二维版本,称作魔板。这是一张有8个大小相同的格子的魔板:1234 8765 我们知道魔板的每一个方格都有一种颜色。这8种颜色用前8个正整数来表示。可以用颜色的序列来表示一种魔板状态,规定从魔板的左上角开始,沿顺时针方向依次取出整数,构成一个颜色序列。对于上图的魔板状态,我们用序列(1,2,3,4,5,6,7,8)来表示。这是基本状态。这里

题目传送门【题意】给出n个二维平面上的坐标,求出这n个坐标最多能够构成多少个正方形。【解题思路】自己完全不会做,只好看网上题解了,现在把Hash和二分的解法展示如下,首先说一说解题的思路,通过n最大为1000可以推测,应该是n^2左右的效率,所以我们先枚举两个点,然后通过这两个点再求出另外两个点的坐标,在输入的集合中查找是否存在这两个点,如果存在的话就可以构成一个正方形。但是枚举也有一定的方法,我
