java - printing out all higher values in a binary search tree by Cyril Blidgestone - Sun, 27 Mar 2016 19:54:43 EST ID:jhX9zOrD No.35395 Ignore Report Reply Quick Reply

how would i go about writing a recursive method to print out all higher values of an input in a binary search tree?

i know i need to make a new list and add the values in as i get them but i have no idea how i should go about moving through the tree to find/add them.

any help would be hugely appreciated

You don't need to make a new list, that kind of defeats the purpose of making your method recursive.

Your method will start by being called on the root of your tree
if the value of the node is less then or equal to the supplied value, you will just call your method on the right node
otherwise you will call your method on the left node, then print the value of the node, then call your method on the right node

my friend, who is not good at programming, needs to programme a shell script for a university project. This is an "off-topic" class, but if he doesn't pass, he's out.

So I decided to help him and make it for him. I'm not familiar with shell also, so I decided to write here to ask for a piece of advice. I would be very glad, if u could look on the script expected output and tell what method I should use to programme it. I just need a skilled experienced eye to look at it, so I know the direction I should go.
Thank you, 420, you've been always very helpful, even though I only asked for adviced on drugs threads

Open Source version of Speed-Reading Add-On. by Beatrice Cellerstire - Sun, 20 Mar 2016 16:54:38 EST ID:U+wWNs50 No.35337 Ignore Report Reply Quick Reply

So I'm a fan of increasing my reading speed. I found this proprietary add-on (therefore likely a botnet) called Bee-line Reader.

"BeeLine Reader makes reading faster and easier by using a color gradient that guides your eyes from the end of one line to the beginning of the next. With BeeLine Reader, you can finish your work faster—and with less eyestrain."

The way it works is that when you click the Bee-line Reader button in your browser, then it makes the article your reading have a slowly evolving color for your text. The first character's color will have an RGB value of (0, 0, 0), but the very next character will have an RGB value of (1, 0, 0) and this will largely increase until the Red value reaches 255, and goes back down to zero, and then the Blue value will rise to 255 and go back down to zero, all the while, the Green value doesn't move much at all.

Since it comes with a faggy 30-day trial period, I've been trying to reverse engineer it's process. I'm not very smart in areas of programming, but with Vim I was able to create a macro that created all 255 Red values going up, and the other 255 Red values going down, and doing the same for the other 255+255 Blue values, resulting in a basic grid, where I just need to figure how to insert text I actually want to read into it, except that for some reason my basic grid doesn't seem to work at all.

This is what my grid looks like:

And this is the failed attempt of an html page that results:

Welcome back, If you say you're not smart in the area of programming do you mean you don't want to learn doing it yourself and want somebody here to write it for you?
Then good luck.

Otherwise what language are you most comfortable with?

Approaches that would work
  • greasemonkey
  • native browser plugin
  • a patch for the rendering engine of your application
  • a proxy injecting tags into your, for instance html document
  • write your own document reader from scratch

No. I want to learn. I don't much about any languages. I kindof, sortof, not-really understand perl, hence the scalars of $character.
I made my grid with a vim macro and vim's incremental character increase and decrease, but I didn't mention that, because I didn't think it was helpful to understanding my goal.

Then the approach where you're using a proxy to modify the html/css will probably the most realistic to accomplish. You might have to come up with something smart in css to handle line breaks correctly.
I can't help you with the CSS part, so you probably better wait for somebody who knows this stuff to come along, I also don't use perl, so...

But curious effect, overall. A thing for my in the back of the head bucket list, thanks.

I don't know what you're trying to read, but if it's anything academic, and it has exercises to test your knowledge of said material then if you want to "increase the speed" what you do is this:

  • Open to random chapter. Attempt the first exercises you find.
  • If pass, continue doing exercises.
  • If stumped, research the problem until you can solve it.
  • Go back to 2 and continue doing exercises.

This is how you fly though something like Concrete Mathematics by Knuth or Algorithms by Rivest et all. It also teaches you a valuable skill which is researching, since you will be confronted with things in life that require knowing how to efficiently look them up.

When certain installers (usually Microsoft's own) run, they will create a Hiberfile on your main system drive. You can check and see if the Hiberfile is there by seeing if "\hiberfil.sys" exists. If it does, you can use the command "powercfg -h off" into an Administrator command-prompt (this will also disable your computer's ability to use the Hibernate feature, however Sleep mode will still be available).

Additionally, Windows Update takes a lot of space after you've installed updates (it's slow to remove things afterwards). You can free up disk space by using the built-into-Windows utility "Disk Cleanup". Find it in your Start Menu, and if you're on Windows 10, select "Clean up System FIles" from the main page of Disk Cleanup. Check all of the checkboxes that you feel comfortable checking, and press Ok to delete all of that stuff.

No, Hiberfile.sys is only used for hibernation, and never exceeds the size of your RAM.

Windows update does install a lot of temporary files. In win7/2008 R2, these are removed with the Disk Cleanup tool, but only if the system is properly updated. This update is KB 2852386.

OP, if that's a screenshot from your PC, do upgrade from Vista.... It was pretty notorious for exactly this...

VOB videos ripped directly from DVDs should be just MPEG2 videos. It should be extremely possible to convert a VOB losslessly into another MPEG video container.

In fact, if you take the .vob file and rename it to .mpg, many video players will recognize that and play the file. And there, now you've just "converted it" without changing its quality at all.

Hey /prog/,

I want to make a custom Novation Launchpad thingy to learn new stuff, but I'm wondering about the communication with a computer. I thought Bluetooth would be good, but the device would have to be powered by an external source. So naturally, USB comes into the picture, which would act as a power supply and means of communication.

I'm not sure whether it is good to use an intermediary board like Arduino or RPi or skip it altogether and wire the usb interface myself.

Speaking of which, how do I go about writing drivers for this stuff? I would like it to be usable both for Linux/Windows.

So I modded a cigar box to fit my kindle fire, then later added a small bluetooth keyboard and bam. instant laptop. It's the shit and I'm not ashamed of showing it off.

I got a BASIC programming app for it and it works great (a few minor bugs) and even came with some sweet code snippets and samples. However, I'm having trouble finding BASIC forums on the web. all I can find is VB shit and that's not going to help me.

specifically I'm having trouble with a do until loop with some if statments inside it.
for some reason the until doesnt register after the ifs. Can you use brackets\braces\parentheses? tried those a few ways and it wouldnt work

BASIC (not VB) forums and such, where are they?

If you are doing it for sports get a Sharp PC-U6000 or one of the even older models and use that. It's more fun when you are restricted by 32kb of program memory :-)

Also, although I haven't tried there's MSX basic, with a quite active scene around them. Seriously if you code basic you do it on a vintage machine or at least an emulator.
And you learn it by reading the Handbook, as they are very simple languages (Different variants of BASIC) which you can learn to grasp in their entirety which is quite something considering the complexity of modern languages.

OP here. got the programming on the kindle thing figured out.
but now I have a new problem

turning on bluetooth isn't difficult, but takes like 8 swipes\taps and that's 6 too many for me. in the BASIC app, the code to turn on Bluetooth is "BT.OPEN", then, if your bluetooth isn't on, you are asked permission to turn it on. Simple! only 2 taps. HOWEVER, I can't for the life of me find a way to open a text file directly from the homescreen. (Though if you open it through the file explorer it will actually open it from the BASIC app by default, sweet!) I'm looking into getting android studio on my computer to just build my own simple apps like this, but it kind fo defeats the purpose of this project.

anybody know anything bout that?
