Minimum One Bit Operations to Make Integers Zero SOLUTION
Given an integer n, you must transform it into 0 using the following operations any number of times:
Change the rightmost (0th) bit in the binary representation of n.
Change the ith bit in the binary representation of n if the (i-1)th bit is set to 1 and the (i-2)th through 0th bits are set to 0.
Return the minimum number of operations to transform n into 0.
Example 1:
Input: n = 0
Output: 0
Example 2:
Input: n = 3
Output: 2
Explanation: The binary representation of 3 is “11”.
“11” -> “01” with the 2nd operation since the 0th bit is 1.
“01” -> “00” with the 1st operation.
Example 3:
Input: n = 6
Output: 4
Explanation: The binary representation of 6 is “110”.
“110” -> “010” with the 2nd operation since the 1st bit is 1 and 0th through 0th bits are 0.
“010” -> “011” with the 1st operation.
“011” -> “001” with the 2nd operation since the 0th bit is 1.
“001” -> “000” with the 1st operation.
Example 4:
Input: n = 9
Output: 14
Example 5:
Input: n = 333
Output: 393
Constraints:
0 <= n <= 109
