I really don't understand want you actually want but from the look of things, if I'm correct you want to use a #URL system in your page. So I assume you want the page viewport to be on blog0 div when the user clicks on

The recursive algorithm is a top down algorithm.

True, the problem is still solved with the bottom of the heap getting sorted out first, and only then the top of the heap, but this is not in contradiction with a top down approach.

In general, the first "problem" that gets solved with a recursive algorithm, is one that occurs in the leaves of its recursion tree: once you a problem is found that can be solved, it back tracks. And the last problem that is solved, is the initial problem with which that recursive algorithm is started. This is typical for recursive algorithms.

The characteristic of a top down algorithm is that it starts by looking at the top-level, "big" problem, and then decides to break it down into one or more "easier" problems, which are then tackled recursively. When those solutions become available the top level problem can be solved also.

An inductive algorithm does not start with the top level problem. It immediately addresses an "easy" problem, and solves that first. Then that solution is used to solve a next problem...etc.

It is true that the order in which subproblems are solved may turn out to be the same order for both approaches. But that order is not what defines an algorithm to be top down or bottom up. The key is: which is the problem that the algorithm addresses first; not what it solves first.

When speaking of heap construction, the terms bottom up and top down are also used in a different way. They then refer to the part of the heap that is constructed first. This can be confusing...

Even though there is a (less efficient) heap construction algorithm that repeatedly increases the size of a heap by adding one element to it with the normal heap_insert algorithm, this is not a true top-down algorithm:

What about this:

Am I right in thinking this code forces the removal of the www.

Yes, but only for HTTP (not HTTPS) requests, as governed by the first condition %{HTTPS} !=on.

If you are implementing HTTPS then you should remove the first condition and change the RewriteRule substitution string to redirect to https://.... But if you are wanting to redirect to www then you'll need to reverse the logic also:

Both the trainer and the jockey have to appear just once in the list (unless the input has duplicate lines).

So, let's just count the occurrences of trainers. To be able to match them to jockeys, we'll store jockeys to trainers in a hash of hashes.

Once we build the two structures, just select the jockeys with only one associated trainer and check that the trainer appeared just once, which had to be with the jockey they were associated to.

There are several ways to accomplish this depending on your preference. The biggest issue you're facing, is that you assume the dropdown-content should know the width of it's parent. An absolute positioned element can only know the width of it's parent under certain conditions - and those conditions aren't being met.

Option #1. (Simplest) way to make the the drop-down the same width is to set a fixed width to your class (.dropdown-content) that matches the fixed width of your button that activates it.

Option #2. A more (Dynamic) way is to set the parent class (.dropdown) a position:relative. Due to your structure, there are several other changes you'll have to make to get the desired result such as getting rid of the overflow:hidden on .navbar & .dropdown.

Option #3. The (Recommended) way would be changing your structure of the Nav Bar & it's contents completely. The .navbar should be position:absolute or position:fixed (depending on how you want the nav bar to behave.) Then each of the .dropdown buttons can be position:absolute or position:relative. Then, your .dropdown-content can be set to width:100%. (Which is the behavior you're looking for).

The function array_walk_recursive will ignore the parent keys. So i think the best method is to write a new recursive function, that will not ignore them. The function array_to_csv below iterates over the part of your array, adds the key to the output (if it is not numeric because: the tel numbers will have 0 and 1 etc as keys). Then it checks if the actual value is an array and calls the function recursive. If it is not an array, it adds the value to the output. After that it returns the result.

The function:

You don't have a () after val for name like you do on the other variables.

Change var userName = $('#text').val; to var userName = $('#text').val();

That will fix your name problem.

Also noticed that you don't have a # in your jquery selector for selection.

Change var selection = $("list").val(); to var selection = $("#list").val();
