Given a number N. Find the number of operations required to reach N starting from 0. You have 2 operations available:

  • Double the number
  • Add one to the number


Example 1:

Input:
N = 8
Output: 4
Explanation: 0 + 1 = 1, 1 + 1 = 2,
2 * 2 = 4, 4 * 2 = 8


​Example 2:

Input: 
N = 7
Output: 5
Explanation: 0 + 1 = 1, 1 + 1 = 2,
1 + 2 = 3, 3 * 2 = 6, 6 + 1 = 7


Your Task:
You don't need to read input or print anything. Your task is to complete the function minOperation() which accepts an integer N and return number of minimum operations required to reach N from 0.


Expected Time Complexity: O(LogN)
Expected Auxiliary Space: O(1)


Constraints:
1 <= N <= 106
