The Hamming distance between two integers is the number of positions at which the corresponding bits are different.
Given two integers x and y, calculate the Hamming distance.
Note:
0 ≤ x, y < 231.
Example:
Input: x = 1, y = 4 Output: 2 Explanation: 1 (0 0 0 1) 4 (0 1 0 0) ↑ ↑ The above arrows point to positions where the corresponding bits are different.

思路很简单,先转成二进制,然后计算异或,然后看一共有多少个1 就是结果了
class Solution(object):
def hammingDistance(self, x, y):
return ((bin(x ^ y)[2:])).count('1')
"""
:type x: int
:type y: int
:rtype: int
"""

本文介绍了一种计算两个整数之间汉明距离的方法。通过将整数转换为二进制形式并进行异或操作,然后计算结果中1的个数来得出汉明距离。适用于范围内的任意两个整数。
