// 给你一个整数 n ,对于 0 <= i <= n 中的每个 i ,计算其二进制表示中 1 的个数 ,返回一个长度为 n + 1 的数组 ans
|
||||
// 作为答案。 示例 1: 输入:n = 2 输出:[0,1,1] 解释: 0 --> 0 1 --> 1 2 --> 10
|
||||
//
|
||||
// 示例 2:
|
||||
// 输入:n = 5
|
||||
// 输出:[0,1,1,2,1,2]
|
||||
// 解释:
|
||||
// 0 --> 0
|
||||
// 1 --> 1
|
||||
// 2 --> 10
|
||||
// 3 --> 11
|
||||
// 4 --> 100
|
||||
// 5 --> 101
|

//
|
||||
// 提示:
|
||||
// 0 <= n <= 105
|
||||
//
|
||||
// 进阶:
|
||||
// 很容易就能实现时间复杂度为 O(n log n) 的解决方案,你可以在线性时间复杂度 O(n) 内用一趟扫描解决此问题吗?
|
||||
// 你能不使用任何内置函数解决此问题吗?(如,C++ 中的 __builtin_popcount )
