693. Binary Number with Alternating Bits
Given a positive integer,check whether it has alternating bits: namely,if two adjacent bits will always have different values. Example 1: Input: 5 Example 2: Input: 7 Example 3: Input: 11 Example 4: Input: 10 class Solution: def hasAlternatingBits(self,n): """ :type n: int :rtype: bool """ s = bin(n) for i in range(2,len(s)-1): if s[i]==‘1‘: if s[i+1]!=‘0‘: return False else: if s[i+1]!=‘1‘: return False return True (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
