题目传送门 /* 题意:给一个串,只能是0,1,?(0/1).计算格雷码方法:当前值与前一个值异或,若为1,可以累加a[i],问最大累加值 DP:dp[i][0/1]表示当前第i位选择0/1时的最大分数,那么分类讨论,情况太多,看代码,注意不可能的状态不要转移 */ /************************************************ * Author :Running_Time * Created Time :2015-8-11 15:49:03 * File N…

题目连接 : 传送门 题意: 给定一个长度为的二进制串和一个长度为n的序列a[],我们能够依据这个二进制串得到它的Gray code. Gray code中假设第i项为1的话那么我们就能够得到a[i]的值,在原来的二进制串中有一些位置为? 表示能够为0, 也能够为1求最后所能得到的最大的值. 已知二进制码怎样得到Gray code请看:传送门 分析: 我们能够通过动态规划来解决问题,状态转移也很好找 ,dp[i][j]表示到第i个位置.第i个位置 取j所能得到的最大值.非常明显这个题的j仅仅能有…

Gray CodeThe gray code is a binary numeral system where two successive values differ in only one bit. Given a non-negative integer n representing the total number of bits in the code, print the sequence of gray code. A gray code sequence must begin w…

Problem Description The reflected binary code, also known as Gray code after Frank Gray, is a binary numeral system where two successive values differ in only onebit (binary digit). The reflected binary code was originally designed to prevent spuriou…
