The AdSense code can not be put only in the title or body of the post or its end, but you can also put it to the left of 'article, see how: 

Simply, once wrote the 'article should include the AdSense code contained in the following tags: 
<span style='float: left; margin: 8px 8px 8px 0px;'>
Adsense Code 
</ Span>
But if you want to put ads on the right rather than left with enough change left to right, and as margins 8px 0px 8px 8px, as follows: 
<span style='float: right; margin: 8px 0px 8px 8px;'>
Adsense code adapted
</ Span>
I hope to be helpful and comprehensive.
