Simple Insertion Sort with PHP Example

admin — Wed, 08 Feb 2012 07:59:45 +0000

Insertion sort is efficient algorithm for sorting a small number of elements. Typical example is sorting cards.

// The array to be sorted
$array = array(5, 2, 4, 6, 1, 3);

foreach($array as $i => $value){
        $j = $i + 1;
        while (($j < count($array) && ($array[$j] < $array[$i])))
        {
            $tmp = $array[$i];
            $array[$i] = $array[$j];
            $array[$j] = $tmp;

            if ($i > 0)
            {
                $i--;
            }
            $j--;
        }
}

print_r($array);

PHP Array Flip – Array Value Key Flip

admin — Fri, 27 Jan 2012 20:19:41 +0000

PHP example that you can use to flip the values and keys in an array. Essentially all the values will become keys and all the keys will become values.

$sampleArray = array(0=>”one”, 1=>”two”, 2=>”three”);

$flipedArray = array_flip($sampleArray);

Java Rotate Shift Integer Values Left

admin — Sat, 19 Nov 2011 03:00:15 +0000

Here is a simple method that rotates/shifts the values of an integer to the left by a certain number. The reason why I am using long for the type of the integer is so that the method works with really big numbers. The returned value is the one that has been rotated. Feel free to replace long with int if you are not going to be working with big numbers. Here is the method:

public static long rotateNumber(long d , int rotateBy)

{

String num = Long.toString(d);

int lenght = Long.toString(d).length();

char[] charArray = new char[lenght];

int count = 0;

for (int i = 0; i < lenght; i++) {

if(i < lenght – rotateBy){

charArray[i] = num.charAt(i + rotateBy);

}else{

charArray[i] = num.charAt(count);

count++;

}

String newNum = new String(charArray);

return Long.valueOf(newNum);

}

public static long rotateNumber(long d , int rotateBy)

{

String num = Long.toString(d);

int lenght = Long.toString(d).length();

char[] charArray = new char[lenght];

int count = 0;

for (int i = 0; i < lenght; i++) {

if(i < lenght – rotateBy){

charArray[i] = num.charAt(i + rotateBy);

}else{

charArray[i] = num.charAt(count);

count++;

}

String newNum = new String(charArray);

return Long.valueOf(newNum);

}

Array Unique Tool – Removes duplicate values from an array online

admin — Mon, 25 Apr 2011 19:00:26 +0000

This is hopefully one of the many online array tools that I am going to publish. In my work I deal with arrays on daily basis. Therefore I have decided to create a simple page where you can manipulate an array in any way I can think of. I am presenting to you the first tool called “Array Unique Tool”. The link is http://erunways.com/online-array-tools/. Enjoy and let me know if you have any suggestions what so ever.

Best Project Management Solution for 2011

admin — Mon, 31 Jan 2011 20:27:30 +0000

A lot has been written lately about this new Free Project Management Solution called Freedcamp. I have to admit I was very excited to hear that there will be a new project management solution that will be absolutely free. I have been looking for something like this for many years. Finally, thanks to the guys at Enavu there is a system for small businesses, start-ups, students, or people who just love to collaborate on ideas. I was “sold” on using Freedcamp as soon as I created my first project. I like the level of details and the website seems to be very responsive. Give it a try, it’s free!

Ubuntu Crontab /etc/crontab Schedule Recurring Tasks

admin — Tue, 26 Oct 2010 05:43:01 +0000

In case you are wondering what the file /etc/crontab do, it is used to schedule tasks to be executed at a certain time with a certain frequency. You don NOT need to reboot the system after you change the file. It will work right a way. Also on a different note Ubuntu doesn’t advise users to use that file for scheduling tasks but you probably do not care and just want to get it going.
