这题解法怎么说呢,由于我是把行数逐步除以2暴力得到的答案,所以有点二分的意思,可是昨天琦神说是有点像分治的意思.反正总的来说:就是从大逐步细化找到最优答案. 可是昨晚傻B了.靠! 多写了点东西,然后就错了,刚才一练习,拿昨晚的代码一看,就把6行代码删去就过了.靠!昨晚应该是脑子进水了!!!!! 昨晚的代码: #include <iostream> #include <cstdio> #include <fstream> #include <algorithm>…

题目链接:http://codeforces.com/contest/426/problem/B 题目意思:给出一个n * m的矩阵a,需要找出一个最小的矩阵b,它能通过several次的mirrorings变成a.mirrorings的操作是这样的:a的upper half(假设行是1-x)部分等于b,lower half(x+1-n部分与upper half 部分对称.对称线处于 x 和 x+1 之间. 很明显,如果矩阵a的行是奇数的话,是找不出 b 的.偶数的时候就通过比较对称的两部分是否…
