sorting

问题 My current code has a checkbox sum function which takes values from database. I am also trying to apply another Javascript code to my table that allows me to sort the data in the rows. For example, after sorting the rows to display all 5 ACER assets on the top. i want tick the checkboxes of the top 5 displayed ACER assets and sum them. This is my current code: <?php include('connect1.php'); $retrieve = $db->prepare("SELECT count(*) FROM Asset"); $retrieve->execute(); $fetchrow = $retrieve-

问题 I have a pretty simple question - I think - but it seems I can't wrap my head around this one. I am a beginner with Python and Pandas. I searched the forum but couldn't get a (recent) answer that fits my need. I have a data frame such as this one: df = pd.DataFrame({'A': [1.1, 2.7, 5.3], 'B': [2, 10, 9], 'C': [3.3, 5.4, 1.5], 'D': [4, 7, 15]}, index = ['a1', 'a2', 'a3']) Which gives: A B C D a1 1.1 2 3.3 4 a2 2.7 10 5.4 7 a3 5.3 9 1.5 15 My question is simple : I would like to add a column

问题 We are given a sorted array. Let the initial value of pass be zero. We can do the following operation any number of times: Select any k numbers at a time. Add them all up. Add this sum to pass If a number, say x , is being selected for the first time from the array, then it is considered as x only. When it is selected for the second time , then it is considered as -x , and for the third time, again as x , and so on... For example, let the array be [-14, 10, 6, -6, -10, -10, -14] and k = 4 ,

问题 I have an array with the following values asd sdf dsdf 1sadf *sdf !sdf @asdf _asd .sadf (sadf )sadf #sadf ^asdf &asdf %asdf -sadf =sadf +sadf -sdf and i want to sort it in javascript in the following way in to three parts. word starting from special character word starting from digit word starting from alphabets. So this should be the sequence of the sorted array. EDIT : Here's a function that I've been experimenting with: function naturalSort(a, b) { a = a.path.toLowerCase(); b = b.path

问题 I am looking for an efficient way to sort a list of strings according a custom alphabet. For example, I have a string alphabet which is "bafmxpzv" and a list of strings composed from only the characters contained in that alphabet. I would like a way to sort that list similarly to other common sorts, but using this custom alphabet. How can I do that? 回答1: Let's create an alphabet and a list of words: In [32]: alphabet = "bafmxpzv" In [33]: a = ['af', 'ax', 'am', 'ab', 'zvpmf'] Now let's sort

问题 Having a brain freeze over a fairly trivial problem. If I start with an array like this: $my_array = array( 'monkey' => array(...), 'giraffe' => array(...), 'lion' => array(...) ); ...and new elements might get added with different keys but always an array value. Now I can be sure the first element is always going to have the key 'monkey' but I can't be sure of any of the other keys. When I've finished filling the array I want to move the known element 'monkey' to the end of the array without
