Removing Duplicate Entries From INT/FLOAT Array?

[sagun-manandhar]

im trying to remove dup items from int or float array

pls hlp

[nowayfra]

int $intArray[] = {1,2,2,2,3,3,4,4,5,6,7,7,7,8,8,9};
int $sortArray[] = sort($intArray);
int $finalArray[] = {$sortArray[0]};

int $tmp = $sortArray[0];
for($i=1;$i<size($sortArray);$i++)
{
    if($sortArray[$i] != $tmp)
    {
        $finalArray[size($finalArray)] = $sortArray[$i];
        $tmp = $sortArray[$i];
    };
};
print $finalArray;

Or you can put the ints in a string array and use stringRemoveDuplicates:

int array duplicates removal using stringArrayRemove

int $intArray[] = {3, 4, 6, 3, 8, 2, 5, 3, 4, 4, 8};
string $stringArray[] = {};
 
for ($i=0; $i<size($intArray); $i++){
     $stringArray[size($stringArray)] = $intArray[$i];
}
 
string $finalStringArray[] = stringArrayRemoveDuplicates($stringArray);
 
int $finalArray[] ={};
for ($int in $finalStringArray){
     $finalArray[size($finalArray)] = $int;
}

Yes but that would just be slow on purose as its a script anyway you can klook it up yourself:

but its here for ease of use

global proc string [] stringArrayRemoveDuplicates(string $list[])
{
	string $item, $result[];
	int    $index = 0;
 
	for ($item in $list) {
		if (0 == stringArrayCount($item, $result)) {
			$result[$index++] = $item;
		}
	}
 
	return $result;
}

so just replace string with int or float or whatever Its recursive so you need to go to the  stringArrayCount function too the difference between theese functions is that the other sorts them in order nowayfra's one not

heh, good point.

To be honest its much easier to do this in python tough.

list(set([1,2,2,2,3,3,4,4,5,6,7,7,7,8,8,9]))

You may wantto keep the set type if you anticipate your data growing.

wow, so many solutions.. btw i already got it but the hard way. finally here is what i wrote. i was trying to identify dup objects..  As you can see i have long lines for removeDuplicateFloatArray() haha.
