题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4708 题目大意:给定一个方形矩阵,边长为3-10的奇数.每一圈的数字可以沿着顺时针方向和逆时针方向旋转,求使得矩阵主对角线和反对角线和最大时的数以及需要旋转的最小步骤. Sample Input 5 9 3 2 5 9 7 4 7 5 4 6 9 3 9 3 5 2 8 7 2 9 9 4 1 9 0   Sample Output 72 1 分析:简单的模拟.分别计算每一圈旋转后的四个角的值最大需…

题意:给出一个n*n的矩阵,旋转每一圈数字,求出对角线可能的最大值,以及转到最大时的最小距离. 只要分析每一层就可以了,本来想用地址传递二维数组,发现行不通,改了一下就行了. 这里有个坑,比如: 1 1 9 9 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 很明显最大的就是将一个9转到矩阵角,而这里更新最大值时很容易把另一种情况屏蔽掉,从而错过了更少步骤达到最大值的方法. 代码: /* * Author: illuz <iilluzen[at]gmail.com> * Blo…

Lock Puzzle 题目大意:给你两个字符串一个s,一个t,长度<=2000,要求你进行小于等于6100次的shift操作,将s变成t, shift(x)表示将字符串的最后x个字符翻转后放到最前面. 思路:不会写,看了题解... 因为长度为3000,操作为6500,我们考虑每三次操作将一个字符放到最后,并保证其他字符的顺序不变,这样是可以实现的, 如果我们想要将第k个字符移到最后,我们只要shift(n-1-k) , shift(1) , shift(n-1),就能实现啦 . #includ…
