基本概念 格雷码是一种准权码,具有一种反射特性和循环特性的单步自补码,它的循环.单步特性消除了随机取数时出现重大误差的可能,它的反射.自补特性使得求反非常方便.格雷码属于可靠性编码,是一种错误最小化的编码方式. 自然二进制码可以直接由数/模转换器转换成模拟信号,但是在某些情况下,例如从十进制的3转换到4的二进制时,每一位都要变.3的二进制位:,而4的二进制位:100,所以这就会使数字电路产生很大的尖峰电流脉冲.而格雷码则没有这一缺点,它是一种数字排序系统,其中的所有相邻整数在它们的数字表示中只有…

题意:给一个二进制数(包含3种符号:'0'  '1'  '?'  ,问号可随意 ),要求将其转成格雷码,给一个序列a,若转成的格雷码第i位为1,则得分+a[i].求填充问号使得得分最多. 思路:如果了解格雷码的转换,相信能很快看出一些端倪.偷别人的图: 分析一下:所给的二进制数要转成格雷码,只与所给二进制有关.即不需要利用已经某些转换好的格雷码字. 接下来分析5个位的串 : (1)00?00 仅有1个问号,只会与后面那些连续且非问号的串转成格雷码有关 (2)00??0 有连续的1个问号,这才需要…
