So given a number count the number of 1's it has set in it's binary representation. Easy!
Just keep on dividing by two (or bitshift right) and see if the number is odd or even and increment the count based
on this criteria like so:

getNumBitsSet(int val) {
 int count=0;
 while(val>0) {
  if(val % 2 != 0)
    count++;
   count = count / 2;

1. mongo
2. use <your-database-name-here>
3. db.addUser('pawel','test')
4. exit
5. vim /etc/mongodb.conf     uncomment the line '#auth=true'
6. sudo service mongodb stop
7. sudo service mongodb start
7.5 Run your application as it is now and verify that it fails since it is missing authentication.
8. in your python code add: db.authenticate('pawel','test')
9. sudo service apache2 restart

If you get tired of typing public class... and then the main method in vim
then here is your solution.

autocmd BufNewFile *.java
  \ exe "normal Opublic class " . expand('%:t:r') . " {\npublic static void main(String [] args) {\n\n}\n}\<Esc>1G"

Just insert it into your '.vimrc' and that's it! The next time you open a brand new Java file you
will see a template.

edit Homestead.yaml and add under sites section
