Ever since his graduation, AKK has been devoting more and more time into investing in cryptocurrencies to pass the time until his start date at the NSA.

In particular, his favorite cryptocurrency is Dogecoin. Being the hacker he is, he was able to find an exploit to artificially create Dogecoin via clandestine transactions. This discovery, along with his desire for Fortnite Gift Cards, has naturally led him to the goal of taking advantage of this exploit to acquire unlimited V-Bucks.

Unfortunately, the methods in which he can create his Dogecoin are limited, as he can only double or add one to his current amount, starting at 0. In addition, he needs to minimize the number of transactions he performs so that his actions won't appear sussy and garner unwanted attention. On top of this, in order to purchase the gift cards, he needs to exchange his Dogecoin to match the exact value of them.

More specifically:

Given a value N, the worth (in Dogecoin) of a Fortnite Gift Card, find the minimum number of transactions needed to acquire N Dogecoin starting with none. Valid transactions include either doubling or adding one to the current amount.

An example is shown below. Given a target value N = 7, the minimum number of transactions to acquire 7 Dogecoin when starting from 0 is 5 transactions.

Input

You will be given target values to attain, representing gift card values.

Example Input

7
8
14
23

Output

For each target value, output the minimum number of allowed transactions required to attain that value, as shown below.

Example Output

1. Minimum number of doge transactions: 5
2. Minimum number of doge transactions: 4
3. Minimum number of doge transactions: 6
4. Minimum number of doge transactions: 8

Algorithmic Complexity

For each input test case, your solution should have the following targets:

Time Complexity O(N), where N is the target number of Dogecoin.
Space Complexity O(N), where N is the target number of Dogecoin.

Your solution may be below the targets, but it should not exceed them.
