当谈到PHP算法演示时,有很多不同的算法可以通过PHP来实现。以下是,安排二分查找排序算法演示示例:
PHP二分查找排序(Quick Sort):
function binarySearch($arr, $x) { $left = 0; $right = count($arr) - 1; while ($left <= $right) { $mid = floor(($left + $right) / 2); if ($arr[$mid] == $x) { return $mid; } elseif ($arr[$mid] < $x) { $left = $mid + 1; } else { $right = $mid - 1; } } return -1; } $sortedArray = [2, 3, 4, 8, 9]; $searchElement = 4; $result = binarySearch($sortedArray, $searchElement); echo "Element found at index: " . $result;
OK!
