The 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 with 0. Ex…

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…

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…

Given a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x. You should preserve the original relative order of the nodes in each of the two partitions. For example, Given 1->4->3->…

Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue. Here, we will use the integers 0, 1, and 2 to represent the color red, white, and bl…
