How to get last level category of each product in magento

I am trying to get last level category name with its product count for each product on listing page. explained as below-

Category
                -> Sub-category 1
                          ->Sub-sub-category 11   -> Product 1
                          ->Sub-sub-category 12 
                              -> Sub-sub-sub-category 13  ->Product 2  
                -> Sub-category 2
                          ->Sub-sub-category 21 
                              -> Sub-sub-sub-category 22  ->Product 3 
                          ->Sub-sub-category 23   -> Product 4

I want to get only categories "Sub-sub-category 11", "Sub-sub-sub-category 13", "Sub-sub-sub-category 22" and "Sub-sub-category 23" which are the last level categories of Products 1, Products 2, Products 3, Products 4. I found below link get last level category name of a product in magento but it only gets third level category.

A little late, but this can be accomplished very simply, use this function when you want to get the category of the deepest level for a given product : 

public function getProductLastLevelCategory(Mage_Catalog_Model_Product $product)
{
    /** @var Mage_Catalog_Model_Resource_Category_Collection $categories */
    $categories = $product->getCategoryCollection()
        ->addAttributeToSelect('*')
        ->addOrder('level');

   return $categories->getFirstItem();
}

The base collection contains all the categories the given product belongs to, and the trick relies on sorting them by level (implicitly DESC).

                echo($_category->getName()."<br />" );
            }
        }
    }
}

$lastCategory = getLastCategory($_storeCategories);
?>

Hi you can use the method getChildrenCount() for your category and check if it's equal to 0

if($category->getChildrenCount() == 0) {
  // Do something
 }
