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…

题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=5375 题目大意:给你一个二进制串,带'?'的位置能够由你来决定填'1'还是'0',补充完整之后转换成格雷码表示,每个位置都有一个权值a[i],仅仅有格雷码为'1'的位能够加上权值,问你终于权值之和最大为多少. 格雷码表示能够百度一下,在这里能够通俗一点讲:对于这么一个串,假设i位置是1,那么他后面的数就会变化(0变1.1变0),注意仅仅是看初始串. 比如:初始串为110,那么改变以后则为101,而…

题意:给一个二进制码,其中有一些位上为'?',对每个问号确定是'0'还是'1',最后以它对应的格雷码来取数,第i位为1则取第i个数,求取得的数的和的最大值. 思路:二进制码B转换成格雷码G的方法是,Gi=Bi^Bi+1,Gn=Bn.所以第i位如果为'?',那么选'1'还是'0'只会影响邻位,于是用dp即可解决. #include <map> #include <set> #include <cmath> #include <ctime> #include &…

题目:格雷码. 格雷码是从0开始且之后两个相邻码之间只有一个符号不相同,例如000,100,101,111三个相邻之间只有一个二进制不同. 现在给定一个数字n,然后给出格雷码所对应的数字.例如: For example, given n = 2, return [0,1,3,2]. Its gray code sequence is: 00 - 0 01 - 1 11 - 3 10 - 2 左边一列是格雷码,右边一列是对应的需要输出的十进制. 我们来观察一下格雷码的规律.如果是1那么是 0 1…
