sorting

问题 I successful implemented sorting and drag & drop, but there fun begins. I need both of them in one list. At this moment it working like ... i can sort (it's ok), i can drag (it's ok) but i can't drop, every time it going back to first position. <table cdkDropList matSort (cdkDropListDropped)="drop($event)" (matSortChange)="sortData($event)"> <tr> <th mat-sort-header="name">Name</th> </tr> <tr *ngFor="let element of sortedData" cdkDrag> <td>{{element.name}}</td> </tr> </table> This is a part

问题 Requirement : I have a Json file which is in .gz format. So, when it is compressed it is around ~500 MB in size. When I extract it, the json file becomes nearly around ~10 GB. The extracted JSON file contains individual JSON objects line by line.What I want is to sort the file based on a field ps using either any bash script or python programs. Because the file is too large, its not advisable to load it into memory. So, I used gzcat and cat bash command to stream the JSON data and then pipe

问题 I have a four vectors that I want to sort in relation to each other. vector<string> color; vector<string> shape; vector<int> size; Each vector is the same size each vector element is tied to each other such that it forms a row {color[0], shape[0], size[0]} {color[1], shape[1], size[1]} {color[2], shape[2], size[2]}, etc So what I am trying to do is sort the color vector by color and sort the other two vectors based on the rearranged color vector. Then within every group of colors (i.e red) I

问题 I have an array and I am sorting it but I need to sort everything except one element of my array. My array is: var Comparison = [ {key: "None", value: "None"}, {key:"Geographical Area", value:"Geographical_Area"}, {key:"Forests", value:"Forests"}, {key:"Barren Unculturable Land", value:"Barren_Unculturable_Land"}, {key:"Land put to Non agricultural use", value:"Land_put_to_Non_agricultural_use"}, {key:"Land Area", value:"Land_Area"}, {key:"Water Area", value:"Water_Area"}, {key:"Culturable

问题 I want to get the rank of each element, so I use argsort in numpy : np.argsort(np.array((1,1,1,2,2,3,3,3,3))) array([0, 1, 2, 3, 4, 5, 6, 7, 8]) it give the same element the different rank, can I get the same rank like: array([0, 0, 0, 3, 3, 5, 5, 5, 5]) 回答1: If you don't mind a dependency on scipy, you can use scipy.stats.rankdata, with method='min' : In [14]: a Out[14]: array([1, 1, 1, 2, 2, 3, 3, 3, 3]) In [15]: from scipy.stats import rankdata In [16]: rankdata(a, method='min') Out[16]:

问题 Given an array of distinct integers.You can remove an element from the array and append it to the end of it.This is one MOVE and counted as one MOVE operation.Find the min no of moves required to sort the array. 回答1: As I understand it, moving an element to the end shifts all elements after that one place, so that moving the third element of [a_1, a_2, a_3, a_4, a_5, a_6] to the end produces [a_1, a_2, a_4, a_5, a_6, a_3] If that understanding is correct, the strategy with the minimum number

问题 What I am trying to do is sort the students' details in a text file based on their first name, id, results and grades. Here is what my Text_File.txt looks like: (each word is separated by tab '\t') rose ramzi 154ss6 85 A john watson 123aq1 96 A+ ellen thomas qs2115 75 B+ I am trying to sort the lines in my text file in ascending order based on the third word (which is the student's ID). I was able to sort the list with the first name and also I could extract the third word and tried using
