1.冒泡排序
function sort($array) {
$length=count($array);
for ($i=$length;$i>0;$i--){
$ swape=true;
for ($j=0;$j<$i-1;$j++){
if ($array[$j]>$array[$j+1]){
$ temp=$array[$j];
$array[$j]=$array[$j+1];
$array[$j+1]=$temp;
$swape=false;🜜
} } if ($swape)break; } return $array;}2.气泡排序function sort($input){ si(!isset ($input)) { return []; } do { $swapped = false; for($i = 0, $count = de($entrée) - 1 ; $i &l; 1], $input[$i]) = [$input[$i], $input[$i + 1]]; $swapped = true; } } } while ($ échangé); return $input;}$array = [51158,1856,8459,67957,59748,58213,90876,39621,66570,64204,79935,27892,47615,94706,34 201,74474,63968,4337 ,43688,42685,31577,5239,25385,56301,94083,23232,67025,44044,74813,34671,90235,65764,49709,12440,21165,20620,38265,12973,2 5236,93144,13720,4204,77026 ,42348,19756,97222,78828,73437,48208,69858,19713,29411,49809,66174,52526277,7515,7873,8350,28229,24105,76818,86897,18456, 29373,7853,24932,93070,4696 ,63015,9358,28302,3938,11754,33679,18492,91503,63395,12029,23954,27230,58336,16544,23606,61349,37348,78629,96145,57954,32 392,76201,54616,59992,5676 ,97799,47910,98758,75043,72849,6466,68831,2246,69091,22296,6506,93729,86968,39583,46186,96782,19074,46574,46704,99211,552 95,33963,77977,86805,72686 ];$array = sort($array);echo implode(',', $array);3.计数排序function sort($array, $min, $max){
$count = array(); for($i = $min; $je <= $max; $i++) { $count[$i] = 0; } foreach($array as $number) { $count[$number]++; } $ z = 0; for($i = $min; $i <= $max; $i++) { while( $count[$i]-- > 0 ) { $array[$z++ ] = $i; } } return $array;}4.插入排序function sort($array){ pour ($i=1;$i
$tableau = [51158,1856,8459,67957,59748,58213,90876,39621,66570,64204,79935,27892,47615,94706,34201,74474,63968,4337,43688, 42685,31577,5239,25385 13720,4204,77026,4 2348,19756,97222,78828,73437 ,48208,69858,19713,29411,49809,3015,9358,28302,3938,11754,33679,18492,91503,63395,12029,23954,27230,58336,16544,23606,613 49,37348,78629,96145,57954 ,32392,76201,54616,59992,5676,97799,47910,98758,75043,72849,6466,68831,2246,69091,22296,6506,93729,86968,39583,46186,9678 2,19074,46574,46704,99211 ,55295,33963,77977,86805,72686];
$array = quickSort($array);
echo implode(',', $array);
6.选择排序
fonction sort ($array) {
$length=count($array);
pour ($i=0;$i<$length;$i++){
$lowest=$i;
pour ($j=$i+1 ;$j<$length;$j++){
if ($array[$j] < $array[$lowest]){
$lowest=$j;
}
}
si ($ i !==$lowest){
$temp=$array[$i];
$array[$i]=$array[$lowest];
$array[$lowest]=$temp;
}
}
return $array;
}
