Problem Statement

Given an integer n, return an array ans of length n + 1 such that for each i (0 <= i <= n), ans[i] is the number of 1's in the binary representation of i.

Example 1:

Input: n = 2 Output: [0,1,1]

Explanation: 0 --> 0 1 --> 1 2 --> 10

Example 2:

Input: n = 5 Output: [0,1,1,2,1,2]

Explanation: 0 --> 0 1 --> 1 2 --> 10 3 --> 11 4 --> 100 5 --> 101

Constraints:

0 <= n <= 105

Follow up:

It is very easy to come up with a solution with a runtime of O(n log n). Can you do it in linear time O(n) and possibly in a single pass? Can you do it without using any built-in function (i.e., like __builtin_popcount in C++)?

Function

class Solution {
public:
    vector<int> countBits(int n) {

    }
};

class Solution:
    def countBits(self, n: int) -> List[int]:

class Solution {
    public int[] countBits(int n) {

    }
}
