What's the fastest way to compare two large lists of 1's & 0's and return the difference count/percentage?

丶灬走出姿态 提交于 2019-12-06 14:21:58
问题 I'm in need of a method to quickly return the number of differences between two large lists. The contents of each list item is either 1 or 0 (single integers), and the amount of items in each list will always be 307200. This is a sample of my current code: list1 = <list1> # should be a list of integers containing 1's or 0's list2 = <list2> # same rule as above, in a slightly different order diffCount = 0 for index, item in enumerate(list1): if item != list2[index]: diffCount += 1 percent =

In what ways member functions may be compared to each other?

末鹿安然 提交于 2019-12-06 13:49:23
问题 I would like to know if I can compare 2 member functions with the "<" operator. I can do "==" but I can't use it in the case below. I tried casting them to void* but that won't work either. template <class Receiver, class Sender> class CallBack2 : public ICallBack2 { protected: Receiver* receiver; void(Receiver::*function)(Sender*); Sender* sender; public: CallBack2(Receiver* _receiver, void(Receiver::*_function)(Sender*), Sender* _sender) : receiver(_receiver), function(_function), sender(

How do you test if 2 large videos are identical?

坚强是说给别人听的谎言 提交于 2019-12-06 12:47:28
问题 I have a system where video files are ingested and then multiple CPU intensive tasks are started. As these tasks are computationally expensive I would like to skip processing a file if it has already been processed. Videos come from various sources so file names etc are not viable options. If I was using pictures I would compare the MD5 hash but on a 5GB - 40GB video this can take a long time to compute. To compare the 2 videos I am testing this method: check relevant metadata matches check

How can I compare two variable strings, would it be like so: $myVar = "hello"; if ($myVar == "hello") { //do code } And to check to see if a $_GET[] variable is present in the url would it be like this" $myVars = $_GET['param']; if ($myVars == NULL) { //do code } $myVar = "hello"; if ($myVar == "hello") { //do code } $myVar = $_GET['param']; if (isset($myVar)) { //IF THE VARIABLE IS SET do code } if (!isset($myVar)) { //IF THE VARIABLE IS NOT SET do code } For your reference, something that stomped me for days when first starting PHP: $_GET["var1"] // these are set from the header location so

java compare objects: using reflection?

你说的曾经没有我的故事 提交于 2019-12-06 11:07:08
I have an object which itself has multiple objects as fields. The question I have is, I have two objects of these kind and I want to compare these two. I know I can do equals, comparator etc. but is there a way to use reflection to get the properties of the object and make comparison. for example, if I have a Car object, which as wheels object, which has tires object, which has bolts object. Please remember all the above objects are individual and not nested classes. How do I compare 2 car objects? Any help is appreciated? Thanks public class Car { private Wheels wheels; // other properties

Compare two text files to find differences and output them to a new text file

I am trying to work on a simple data comparison text document. The goal is for the user to be able to select a file, search through this file for a certain parameter, then print those parameters into a new text document, after compare those parameters from the new text document with a text document that has the default parameters and then once they've been compared to print out the differences into a new text document. I've created a simple flowchart to summarize this: This is my current code. I am using the diff lib to compare the two files. import difflib from Tkinter import * import
