Implementation of PHP Comb Sort algorithm

Mar 09, 2019 am 10:08 AM

Comb sort or comb sort is a variant of Bubble sort . Similar to Shell sort, Comb Sort increases the gap used in comparisons and exchanges. Some implementations use insertion sort when the interval is less than a certain number. The basic idea is to eliminate small values ​​near the end of the list, since in bubble sort these will slow down the sort significantly. And large values ​​at the beginning of the list will not cause problems in bubble sort.

Implementation of PHP Comb Sort algorithm

In bubble sort, when any two elements are compared, they always have a gap of 1. The basic idea of ​​comb sorting is that the gap can be much larger than 1.

PHP comb sorting diagram is as follows:

##The code example is as follows:

<?php
function combSort($my_array){
    $gap = count($my_array);
    $swap = true;
    while ($gap > 1 || $swap){
        if($gap > 1) $gap /= 1.25;
        $swap = false;
        $i = 0;
        while($i+$gap < count($my_array)){
            if($my_array[$i] > $my_array[$i+$gap]){
                list($my_array[$i], $my_array[$i+$gap]) = array($my_array[$i+$gap],$my_array[$i]);
                $swap = true;
            }
            $i++;
        }
    }
    return $my_array;
}
$test_array = array(3, 0, 2, 5, -1, 4, 1);
echo "原始数组 :\n";
echo implode(&#39;, &#39;,$test_array );
echo "\n排序后数组\n:";
echo implode(&#39;, &#39;,combSort($test_array)). PHP_EOL;
Copy after login

Output:

原始数组 : 3, 0, 2, 5, -1, 4, 1
排序后数组 :-1, 0, 1, 2, 3, 4, 5
Copy after login
