问题 How to subtract one list from another? List<string> l1 = new List<string> { "abc", "abc", "abc", "def" }; List<string> l2 = new List<string> { "abc" }; var r = l1.Except(l2).ToList(); Doing this results in r => "def" instead of r=> "abc", "abc", "def". I mean, the second list only contains "abc" one time. So I want to remove only one instance of "abc" of the first list. Btw: Is there a way to check if one list is completely contained in another list? Meaning when list1 only contains "abc" one

问题 I constructed an unordered_map using key type rot3d, which is defined below: #ifndef EPS6 #define EPS6 1.0e-6 #endif struct rot3d { double agl[3]; // alpha, beta, gamma in ascending order bool operator==(const rot3d &other) const { // printf("== used\n"); return abs(agl[0]-other.agl[0]) <= EPS6 && abs(agl[1]-other.agl[1]) <= EPS6 && abs(agl[2]-other.agl[2]) <= EPS6; } }; Equality of rot3d is defined by the condition that each component is within a small range of the same component from the

问题 I wrote a simple method that adds a spinner to the main body of an html page and binds the event to an ajaxstart method then removes it on the ajaxstop. StartAjaxCallSpinner = function (spinnerObj) { var $bod = $("Body"); if ($('#bgSpinnerDiv')[0] == undefined && $('#spinnerHolder')[0] == undefined) { $bod.append("<div id='spinnerHolder' style='display:none;'></div><div id='bgSpinnerDiv'></div>"); } $('#spinnerHolder') .hide() .ajaxStart(function () { $('#bgSpinnerDiv').css({ 'background

问题 I am working on a django/wagtail management command (let's call it "file_upload") that does roughly the following: take "csv" argument, which is a full path to a CSV file. parse and open the result using csv for each row, create and save a custom Wagtail Image model object (inheriting from AbstractImage , with a few extra CharField that I do not think prevent me from doing what I want to do) The (currently simplified) CSV looks like this: 1.jpg,Title 1 2.jpg,Title 2 Does not complicated at
