题目: 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 Explanatio…

▶ 与 Hamming  距离相关的两道题. ▶ 461. 求两个数 x 与 y 的哈夫曼距离. ● 代码,4 ms,对 x 和 y 使用异或,然后求值为 1 的位的个数. class Solution { public: int hammingDistance(int x, int y) { int i,temp; , temp = x ^ y; temp > ; temp &= temp - , i++); return i; } }; ● 代码,7 ms,转化为 bitset 来逐位比…

两个整数的 汉明距离 指的是这两个数字的二进制数对应位不同的数量.计算一个数组中,任意两个数之间汉明距离的总和.示例:输入: 4, 14, 2输出: 6解释: 在二进制表示中,4表示为0100,14表示为1110,2表示为0010.(这样表示是为了体现后四位之间关系)所以答案为:HammingDistance(4, 14) + HammingDistance(4, 2) + HammingDistance(14, 2) = 2 + 2 + 2 = 6.注意:    数组中元素的范围为从 0到 1…

Fun one.. the punch line of this problem is quite common in Bit related problems on HackerRank - visualize it in your mind, and you will find: all bits on the same index among all numbers, will not involve other bits on other indices. So, we simply c…
