0 comments Posted by Opoel34 on Sunday, September 13, 2009
Apakah kamu seorang programmer / setidaknya minimal suka atau membuat program komputer? Terus apakah kamu juga suka tantangan? maka datang dan gabunglah di situs http://uva.onlinejudge.org/. Di situs ini disediakan berbagai contoh permasalahan yang biasa dijadikan materi dalam kontes pemrograman. Disamping itu juga ada kontes berkala yang dapat kamu ikuti. Kalau kamu tertarik tunggu apa apalagi, daftar saja langsung. Terus buat yang  merasa info di sini masih kurang dan masih penasaran ya kunjungi saja langsung alamat situs tersebut.   

Berikut contoh permasalahan yang harus kamu pecahkan:

 The 3n + 1 problem
 


Background

Problems in Computer Science are often classified as belonging to a certain class of problems (e.g., NP, Unsolvable, Recursive). In this problem you will be analyzing a property of an algorithm whose classification is not known for all possible inputs.

The Problem

Consider the following algorithm:

        1.          input n


        2.          print n


        3.          if n = 1 then STOP


        4.                   if n is odd then  


        5.                   else  


        6.          GOTO 2

Given the input 22, the following sequence of numbers will be printed 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1

It is conjectured that the algorithm above will terminate (when a 1 is printed) for any integral input value. Despite the simplicity of the algorithm, it is unknown whether this conjecture is true. It has been verified, however, for all integers n such that 0 < n < 1,000,000 (and, in fact, for many more numbers than this.)

Given an input n, it is possible to determine the number of numbers printed (including the 1). For a given n this is called the cycle-length of n. In the example above, the cycle length of 22 is 16.

For any two numbers i and j you are to determine the maximum cycle length over all numbers between i and j.

The Input

The input will consist of a series of pairs of integers i and j, one pair of integers per line. All integers will be less than 1,000,000 and greater than 0.

You should process all pairs of integers and for each pair determine the maximum cycle length over all integers between and including i and j.

You can assume that no operation overflows a 32-bit integer.

The Output

For each pair of input integers i and j you should output i, j, and the maximum cycle length for integers between and including i and j. These three numbers should be separated by at least one space with all three numbers on one line and with one line of output for each line of input. The integers i and j must appear in the output in the same order in which they appeared in the input and should be followed by the maximum cycle length (on the same line).

Sample Input

1 10
100 200
201 210
900 1000

Sample Output

1 10 20
100 200 125
201 210 89
900 1000 174

Opera 10.00 - Free Web Browser; Info, Download.

0 comments Posted by Opoel34 on Thursday, September 03, 2009
What's new in Opera 10

Opera Turbo for fast browsing on slow connections

Opera Turbo uses compression technology that provides significant improvements in browsing speeds over limited-bandwidth connections, for example, when using a crowded Wi-Fi in a cafe or browsing through your mobile phone while commuting.

New visual tabs and sleek design

Opera has always been the pioneer for how to deal with tabs in your browser. In Opera 10, we introduce a re sizable tab bar. Drag the handle underneath the tabs to reveal thumbnails of your open Web pages. And, because great features should come in beautiful packages, designer Jon Hicks has created a whole new look for Opera 10.


Speed Dial your way

You asked for it! Customize your Speed Dial to fit your own needs. Click the Configure Speed Dial button and choose from 4 to 25 favorite Web sites for quick access every time you open a new tab. You can also add a custom background so that you feel right at home.

Web integration

If you use a Web mail service as your default mail client, you can tell Opera 10 to do the same. Clicking on e-mail addresses or “Send by Mail” in Opera will open the compose page from your Web mail service provider. The same is true with the Feed reader — you can now also add any RSS/atom feed into your favorite online feed reader from within Opera 10.

Resizable search field

Have a clearer view of what you are about to search by simply expanding the size of the search field — because many of life’s questions require more than two words of space.

40% faster engine and cutting-edge Web standards support

We optimized the new Opera Presto 2.2 engine in Opera 10 to be much faster on resource-intensive pages such as Gmail and Facebook. In addition, with an Acid3 100/100 score, Web Fonts support, RGBA/HSLA color and SVG improvements, Opera 10 is ready for the next generation of Web applications.

MPlayer - Free Multi-Platform Movie Player

0 comments Posted by Opoel34 on Tuesday, September 01, 2009
 
Publisher's Description

mplayer is a movie player for Linux (runs on many other platforms and CPU architectures, see the documentation). It plays most MPEG/VOB, AVI, ASF/WMA/WMV, RM, QT/MOV/MP4, Ogg/OGM, MKV, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many native and binary codecs. You can watch VCD, SVCD, DVD, 3ivx, DivX 3/4/5, WMV and even H.264 movies, too.

MPlayer supports a wide range of video and audio output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, libcaca, DirectFB, Quartz, Mac OS X CoreVideo, but you can also use GGI, SDL (and all their drivers), VESA (on every VESA-compatible card, even without X11), some low-level card-specific drivers (for Matrox, 3dfx and ATI) and some hardware MPEG decoder boards, such as the Siemens DVB, Hauppauge PVR (IVTV), DXR2 and DXR3/Hollywood+. Most of them support software or hardware scaling, so you can enjoy movies in fullscreen mode.

MPlayer has an onscreen display (OSD) for status information, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/ISO8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS and our own: MPsub) and DVD subtitles (SPU streams, VOBsub and Closed Captions).

Sometimes it read SMPlayer, others MPlayer, what are they? are they the same?

No, they are two different applications. MPlayer is a multimedia player developed initially for linux and then ported to other OS. It's very good, it plays almost every everything, and it has for instance a lot of filters and so on. But most users may find it hard to use it.

Fortunately MPlayer can work together with another application (the video window can be embedded in the other application GUI, it obeys commands sent by the application). So SMPlayer is just a front-end which uses MPlayer to actually play the videos.

SMPlayer is the window you see, the menus, the preferences dialog... (along with other things you don't see, like functions to control MPlayer). But SMPlayer knows nothing about playing files. It doesn't even know what a codec is. MPlayer on the other hand, opens the files, decodes them, displays the video and plays the audio. Subtitles are also read, parsed and displayed on screen by MPlayer.
