leetcode 上的Counting Bits 总结

最近准备刷 leetcode 做到了一个关于位运算的题记下方法

int cunt = 0;

while(temp)

{

　　temp = temp&(temp - 1); //把二进制最左边那个1变为零

　　count++; //统计1的个数

}

同理把位二进制坐左边那个0变为1

就可以 temp = temp|(temp + 1)

[LeetCode][Java][JavaScript]Counting Bits

Counting Bits Given a non negative integer number num. For every numbers i in the range 0 ≤ i ≤ num calculate the number of 1's in their binary representation and return them as an array. Example:For num = 5 you should return [0,1,1,2,1,2]. Follow up

【Leetcode 338】 Counting Bits

---恢复内容开始--- 问题描述:给出一个非负整数num,对[0, num]范围内每个数都计算它的二进制表示中1的个数 Example:For num = 5 you should return [0,1,1,2,1,2] 思路:这种题适合归纳法,找出规律然后用编程语言描述,令i从0开始,设f(i)为i对应二进制表示中1的个数也就是每次有一个大小为2^n的序列,把他们每个数都加1,然后插入到结尾就构成了大小为2^(n+1)个序列. 直到2^(n+1)比num大,取前num个数组成序列返回即可
