sorting

问题 I am building a classical Nim game. So far, I've done the player part and the game part. Now, I am trying to sort(rank) the object in an array. I've built the following for sorting: playerList winRatio , which is set in the NimPlayer class with its getter. The aim : to sort the winRatio descendingly, which means from the highest score to the lowest one. The ratio is calculated by score/gamePlayed . If there's a tie, sort using userName alphabetically. I've referred to this issue: How to sort

问题 I've got a List<Card> , and I want to sort these cards So, I'm looking for a method to sort them with different criterias, like their ID , their Name ... public class Card : IComparer { public string ID; public string Name; public int CompareId(object firstCard, object secondCard) { Card c1 = (Card)firstCard; Card c2 = (Card)secondCard; return c1.Id.CompareTo(c2.Id); } } But then, visual studio sent me an error : 'Card' does not implement interface member 'IComparer<Card>.Compare(Card, Card)'

问题 My entity class looks like this: public class Student { private int grade; // other fields and methods } and I use it like that: List<Student> students = ...; How can I sort students by grade , taking into account that it is a private field? 回答1: You have these options: make grade visible define a getter method for grade define a Comparator inside Student make Student implement Comparable use reflection (in my opinion this is not a solution , it is a workaround / hack ) Example for solution 3

问题 I'm trying to make a Bingo ticket (Housie) generator, but I've got some problems. Normally, each row contains five numbers and four blank spaces randomly distributed along the row. Numbers are apportioned by column (1–9, 10–19, 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, and 80–90). My generator looks like this: As you can see, I can't manage to have 5 numbers per row. My code is the following (I'm using the RandomPlus class): package com.demstra.Ticket { import flash.display.MovieClip; public

问题 I have two data table and want to sort them such that row value of first table is same as row value of second table based on a column named Parameter . Using order() , the problem is that it will only sort based on the data table input. But to ensure that not only both data tables are sorted based on Parameter column, but are also sorted correctly by comparing the column Parameter row by row between two data tables as a sanity check. Please share any faster way to do this. First Table Input

问题 I have a table with 2 columns, the first column is called ID and the second is called TRACKING . The ID column has duplicates, I want to to take all of those duplicates and consolidate them into one row where each value from TRACKING from the duplicate row is placed into a new column within the same row and I no longer have duplicates. I have tried a few suggested things where all of the values would be concatenated into one column but I want these TRACKING values for the duplicate ID s to be

问题 Experimenting with vimscript and reading the wonderful Learn Vimscript the Hard Way (LVTHW), I realized that Vim wasn't sorting numbers the way I wanted it to. For example this function from LVTHW function! Sorted(l) let new_list = deepcopy(a:l) call sort(new_list) return new_list endfunction surprised me when I called it with Sorted([3, 1, 11, 2]) : It returned [1, 11, 2, 3] . I think Vim sorts those numbers in alphabetical order. But I'd expect the function to return the numbers in natural

问题 For a side-project I want to sort the keys of a JSON with jq, and come up with the following solution: def add_property_prefix: if .key == "beka" then "01__"+.key elif .key == "alma" then "02__"+.key elif .key == "paprika" then "03__"+.key elif .key == "korte" then "04__"+.key else .key end ; def del_property_prefix: .key | sub("^[0-9]{2}__"; "") ; to_entries | map({ key: add_property_prefix, value: .value }) | sort_by(.key) | map({ key: del_property_prefix, value: .value }) | from_entries
