格雷码(Gray Code)是一种二进制编码方式,它使用两种不同状态的信号(通常为 0 和 1)来表示二进制位。与普通的二进制编码不同,格雷码相邻的两个二进制位之间只相差一个比特。 以下是一个使用 Python 实现的格雷码转换示例: def gray_code(n): if n == 0: return [0] else: gc = [] for i in range(...

Can you solve this real interview question? Gray Code - An n-bit gray code sequence is a sequence of 2n integers where: * Every integer is in the inclusive range [0, 2n - 1], * The first integer is 0, * An integer appears no more than once in the seq
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. For example, given n = 2, return [...
