I feel there has to be a more efficient way of checking them rather than one at a time. $jdmMethod = $_POST [ 'jdmMethod' ]; $cmdMethod = $_POST [ 'cmdMethod' ]; $vbsMethod = $_POST [ 'vbsMethod' ]; $blankPage = $_POST [ 'blankPage' ]; $facebook = $_POST [ 'facebook' ]; $tinychat = $_POST [ 'tinychat' ]; $runescape = $_POST [ 'runescape' ]; $fileUrl = escapeshellcmd ( $_POST [ 'fileUrl' ]); $redirectUrl = escapeshellcmd ( $_POST [ 'redirectUrl' ]); $fileName =

Basically automate console.log here is the code: $("button#search").on("click", function(){ var inputVal = $("input#text").val(); $.getJSON("https://en.wikipedia.org/w/api.php?action=opensearch&search=" + inputVal +"&limit=5&namespace=0&format=json&callback=?", function(json) { var itemName = $.each(json[1], function(i, val){ }) var itemDescription = $.each(json[2], function(i, val){ }) var itemLink = $.each(json[3], function(i, val){ }) console.log

Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2] ). You are given a target value to search. If found in the array return its index, otherwise return -1 . You may assume no duplicate exists in the array. Your algorithm's runtime complexity must be in the order of O (log n ). Example 1: Input: nums = [4,5,6,7,0,1,2], target = 0 Output: 4 Example 2: Input: nums = [4,5,6,7,0,1,2], target = 3 Output: -1比较笨的办法, 既然数组被旋转了,找出在哪里旋转的就好.接着就是普通的二分查找,使用stl自带的binary_search也可以.但是本题有一个test case是 [1,3] 3 ????

I have a series of buttons already on my form and I want to use an index to access them...e.g.: myButtonArray [ 0 ]. ForeColor ... // Do something with it Can this be done? Edit: Can I set the array to have a generic OnClick event? And then determine which button in the array was clicked and, say, change its color? 回答1: You can do it the same way as for any other array. For example: Button [] array = { firstButton , secondButton };

Aside from that, the performance of splice is going to vary a lot between implementations (e.g., vendors). This is one reason why "don't

Something like: void foo(size_t limit) { char buffer[limit * 14 + 1]; } But just GCC compiler says: error: ISO C90 forbids variable length array ‘buffer’ searching on SO I found this answer : C99 §6.7.5.2: If the size is an expression that is not an integer constant expression... ...each time it is evaluated it shall have a value greater than zero. So, I did the re-declaration of size limit type variable to: void foo(const size_t limit) But it continues to give warning for me. Is this a GCC

This is what I tried: function arraySum(i) { sum=0; for(a=0;a<i.length;a++){ if(typeof i[a]=="number"){ sum+=i[a]; }else if(i[a] instanceof Array){ sum+=arraySum(i[a]); } } return sum; } Does somebody know where there is a mistake in it? When you try it out with the array [[1,2,3],4,5], it gets 6 as answer, instead of 15. I don't know why. 回答1: The problem with your code is that the sum and a variables are global, instead of local. Because of this

This is the data assigned to my $quantities array: Array( [10] => Array([25.00] => 1) [9] => Array([30.00] => 3) [8] => Array([30.00] => 4) [12] => Array([35.00] => ) [1] => Array([30.00] => ) [2] => Array([30.00] => ) ) I'm looking for a way to remove the subarrays with empty values like [12] [1] and [2] while keeping everything else. The desired result: Array( [10] => Array([25.00] => 1) [9] => Array([30.00] => 3) [8] => Array([30.00] => 4) ) I tried a lot of the

However, at some point along the way my variable gets converted from an array to a string (usually when it hits script2.ps1), and I'm not able to loop thru it. What do I need to do to keep the variable as an array throughout the entire process? Here is the workflow of the variable: Script1.ps1 :
