compare

What is the easiest way to compare the 2 lists/sets and output the differences? Are there any built in functions that will help me compare nested lists/sets? Inputs: First_list = [['Test.doc', '1a1a1a', 1111], ['Test2.doc', '2b2b2b', 2222], ['Test3.doc', '3c3c3c', 3333] ] Secnd_list = [['Test.doc', '1a1a1a', 1111], ['Test2.doc', '2b2b2b', 2222], ['Test3.doc', '8p8p8p', 9999], ['Test4.doc', '4d4d4d', 4444]] Expected Output: Differences = [['Test3.doc', '3c3c3c', 3333], ['Test3.doc', '8p8p8p', 9999], ['Test4.doc', '4d4d4d', 4444]] So you want the difference between two lists of items. first_list

I have 2 lists, both of which contain same number of dictionaries. Each dictionary has a unique key. There is a match for each dictionary of the first list in the second list, that is a dictionary with a unique key exists in the other list. But the other elements of such 2 dictionaries may vary. For example: list_1 = [ { 'unique_id': '001', 'key1': 'AAA', 'key2': 'BBB', 'key3': 'EEE' }, { 'unique_id': '002', 'key1': 'AAA', 'key2': 'CCC', 'key3': 'FFF' } ] list_2 = [ { 'unique_id': '001', 'key1': 'AAA', 'key2': 'DDD', 'key3': 'EEE' }, { 'unique_id': '002', 'key1': 'AAA', 'key2': 'CCC', 'key3':

I have 2 arrays, the value will be loaded from database, below is an example: $arr1 = array(1,2,3); $arr2 = array(1,2,3,4,5,6,7); What I want to do is to check if all the values in $arr1 exist in $arr2 . The above example should be a TRUE while: $arr3 = array(1,2,4,5,6,7); comparing $arr1 with $arr3 will return a FALSE . Normally I use in_array because I only need to check single value into an array. But in this case, in_array cannot be used. I'd like to see if there is a simple way to do the checking with a minimum looping. UPDATE for clarification. First array will be a set that contains

I have a simple question regarding xcode coding but don't know why things are not performing as I think. I have an array of objects (custom objects). I just want to check if this one is within the array. I used the following code: NSArray *collection = [[NSArray alloc] initWithObjects:A, B, C, nil]; //A, B, C are custom "Item" objects Item *tempItem = [[Item alloc] initWithLength:1 width:2 height:3]; //3 instance variables in "Item" objects if([collection containsObject:tempItem]) { NSLog(@"collection contains this item"); } I suppose the above checking will give me a positive result but it's

1.JSON Viewer 用来格式化JSON的 使用: 插件->JSON Viewer->FormatJSON; 2.XML Tools 用来格式化XML文件的 使用:插件->XML Tools->Pretty print(XML only - with line breaks) 3.Compare 用来比较两个文件,和Beyond Compare 4差不多. 插件->Compare->Compare; 来源： https://www.cnblogs.com/lishuaiqi/p/11363003.html

So we got this function in PHP strcmp(string $1,string $2) // returns -1,0, or 1; We Do not however, have an intcmp(); So i created one: function intcmp($a,$b) { if((int)$a == (int)$b)return 0; if((int)$a > (int)$b)return 1; if((int)$a < (int)$b)return -1; } This just feels dirty. What do you all think? this is part of a class to sort Javascripts by an ordering value passed in. class JS { // array('order'=>0,'path'=>'/js/somefile.js','attr'=>array()); public $javascripts = array(); ... public function __toString() { uasort($this->javascripts,array($this,'sortScripts')); return $this->render();

I need a tool for comparing 2 binary files. The files are quite big. Some freeware or trial tools I found on internet are not convenient to use for big files. Can you recommend me any tools? Polynomial A few possibilities: VBinDiff (binary diff, designed for large files) WinDiff bsdiff HexCmp See also: https://web.archive.org/web/20151122151611/https://stackoverflow.com/questions/688504/binary-diff-tool-for-very-large-files Mike Woinoski If you want to find out only whether or not the files are identical, you can use the Windows fc command in binary mode: fc.exe /b file1 file2 For details, see
