TOJ 2776题目链接http://acm.tju.edu.cn/toj/showp2776.html 这题其实就是考虑的周全性...  贡献了好几次WA, 后来想了半天才知道哪里有遗漏.最大的问题就是, 当零头是13的时候, 不一定前面的光盘都刻录到最大值.比如29,16这种情况, 如果前面的刻录最大值,这样就需要3个盘,而最少的却是 2个就够了,(15,14) 即可:知道这种情况,这题基本就可以了: 注意一下这几个数据: 13 15 输出为2 29 16 输出为2 这条题目看起来很容易,但…

题意:4*4的正方形,每个格子有黑白两面,翻转格子使得4*4个格子显示全黑或全白,翻转要求:选中的那个格子,以及其上下左右相邻的格子(如果存在)要同时翻转.输出最小的达到要求的翻转次数或者Impossible(如果不可能) 题目链接:http://poj.org/problem?id=1753 分析:因为每个格子只有黑白两面,所以对于每个格子来说,要么不翻转,要么翻转一次,因为翻转奇数次结果和翻转一次得到的效果是一样的,而翻转偶数次得到的效果和不翻转是一样的,则总共有16个格子,最多要翻转16次…

对缓冲区的读写操作首先要知道缓冲区的下限.上限和当前位置.下面这些变量的值对Buffer类中的某些操作有着至关重要的作用: limit:所有对Buffer读写操作都会以limit变量的值作为上限. position:代表对缓冲区进行读写时,当前游标的位置. capacity:代表缓冲区的最大容量(一般新建一个缓冲区的时候,limit的值和capacity的值默认是相等的). flip.rewind.clear这三个方法便是用来设置这些值的. clear方法 } 以上三种方法均使用final修饰,…
