find element by xpath

not super concise.If you don't think it's enough:var LCM = function (){var numbers = Array.prototype.slice.call (arguments);if (!numbers.length)return null;if (! Math.min.apply (null, numbers))return 0;Return Numbers.reduce (Lcmof2numbers, Numbers.pop ());};var lcmof2numbers = function (Number1, number2){Return number1 * number2/gcdof2numbers (Number1, number2);};var gcdof2numbers = function (Number1, number2){Return!number2? Number1:gcdof2numbers (number2, number1% number2);};So is it possible

Binary find whether an array contains an element, compatible positive and negative sequence, code implementation: Copy Code code as follows: $searchValue = (int) $_get[' key ']; function search (array $array, $value) { $max = count ($array)-1; $min = 0; $isAscSort = $array [$min] while (TRUE) { $sum = $min + $max; $midKey = (int) ($sum%2 = = 1 Ceil ($sum/2): $sum/2); if ($max ret

Idea: first set sorting, time complexity Nlogn, and then the M from the maximum start to traverse, A and b respectively take less than m minimum and maximum, test whether the a+b is equal to M, if the small a right shift, if the big B shift left. The total time responsibility is n*nint find (int s[], int n) {sort (s, S + N); for (int i = n-1; I >=2; i.) {int left = 0, right = I-1;while (left Copyright NOTICE: This article for Bo Master original artic

int [] [] Array ={{1,2,8,9},{2,4,9,12},{4,7,10,13},{6,8,11,19}};In a two-dimensional array, each row is ordered in ascending order from left to right, and each column is sorted in ascending order from top to bottom. Complete a function, enter a two-dimensional array and an integer to determine if the array contains the integer.public class Solution {public static Boolean Find (int target, int []] array) { int M = array.length; int N = arr

The Find A-element method is very right, you can pass the ID or class, but if neither of the two conditions, there is no way?

want this code to run directly when it is loaded, consider the order of execution, either onload executes it or put it behind HTML.And why is it easy to use after alert? Because the alert execution time, waiting for the user to confirm the process, the program is blocked, do not go down, but the page loading process is not aborted, which is equivalent to the page loading and parsing time, was alert to stay, if the user's deft on hand, and the network speed is very slow, the same will be error,
