Codeforces 579A Raising bacteria

A. Raising bacteria

You are a lover of bacteria. You want to raise some bacteria in a box.

Initially, the box is empty. Each morning, you can put any number of bacteria into the box. And each night, every bacterium in the box would split into the bacteria. You hope to see exactly x bacteria in the box at some moment.

What's the minimum number of bacteria you need-put into the box across those days?

Input

The only line containing one integer x (1≤ x ≤10^9).

Output

The only line containing one integer:the answer.

Sample Test (s) Input

5

Output

2

Input

8

Output

1

Note

For the first sample, we can add one bacterium in the "The first day Morning" and at the third morning there would be 4 bacteria in the box. Now we put one more resulting 5 in the box. We added 2 bacteria in the process so that the answer is 2.

For the second sample, we can put a one in the first morning and in the 4-th morning there would be a 8 in the box. So the answer is 1.
