题目描述
Given a number N, print all the numbers which are a bitwise subset of the binary representation of N. Bitwise subset of a number N will be the numbers i in the range 0 ≤ i ≤ N which satisfy the below condition:
N & i == i
Example 1:
Input:
N = 5
Output: 5 4 1 0
Explanation:
0 & 5 = 0
1 & 5 = 1
2 & 5 = 0
3 & 5 = 1
4 & 5 = 4
5 & 5 = 5
Example 2:
Input:
N = 9
Output: 9 8 1 0
Your Task:
You don't need to read input or print anything. Your task is to complete the function printSubsets() which takes the integer N as input parameters and returns the array of integers that satisfy the above condition.
Expected Time Complexity: O(K), where K is the number of bitwise subsets of N.
Expected Auxiliary Space: O(1)
Constraints:
1 ≤ N ≤ 10000
