alphabetical

问题 This is not based on efficiency, and has to be done with only a very very basic knowledge of python (Strings, Tuples, Lists basics) so no importing functions or using sort/sorted. (This is using Python 2.7.3). For example I have a list: unsort_list = ["B", "D", "A", "E", "C"] sort_list = [] sort_list needs to be able to print out: "A, B, C, D, E" I can do it with numbers/integers, is there a similar method for alphabetical order strings? if not what would you recommend (even if it isn't

问题 I have been given a large text as input. I have made a HashMap that stores each different word as a key, and number of times that occurs as value (Integer). Now I have to make a method called mostOften(int k):List that return a List that gives the first k-words that from max number of occurrence to min number of occurrence ( descending order ) using the HashMap that I have made before. The problem is that whenever 2 words have the same number of occurrence, then they should be sorted

问题 I have been working through Chris Pine's tutorial for Ruby and am currently working on a way to sort an array of names without using sort . My code is below. It works perfectly but is a step further than I thought I had got! puts "Please enter some names:" name = gets.chomp names = [] while name != '' names.push name name = gets.chomp end names.each_index do |first| names.each_index do |second| if names[first] < names[second] names[first], names[second] = names[second], names[first] end end

问题 Is it possible to sort all ListViewGroups of a Windows Forms ListView alphabetically at runtime? Or do I have to manually implement sorting when I'm adding a group (using the "Insert" method of the ListViewGroupCollection)? If this is the case, can someone give me an idea how to do this? 回答1: In WinForms ListView, you have to do the sorting manually: ListViewGroup[] groups = new ListViewGroup[this.listView1.Groups.Count]; this.listView1.Groups.CopyTo(groups, 0); Array.Sort(groups, new

问题 I'm trying to sort an array of phrases in Esperanto by alphabetical order. Is there a way to use sort_by to accomplish this? I'm checking each character of the string against its index in the Esperanto alphabet, with each increasing index being a step lower in sorting priority: esp_alph = " abcĉdefgĝhĥijĵklmnoprsŝtuŭvz" arr.sort_by {|string| [esp_alph.index(string[0]), esp_alph.index(string[1]), esp_alph.index(string[2]), esp_alph.index(string[3])]} However, this isn't a scalable solution,

问题 I am using jQuery to insert rows into a table after a database insert. When the page loads the table is ordered alphabetically on a particular cell (see below). When I insert a new row using jQuery I would like to be able to insert it alphabetically also. So for example I have a table with <tbody> elements similar to this: <tbody> <tr class="docRow" bgcolor="#EFE5D3" style="font-weight: bold; font-size: 1.1em;"> <td width="25px"><a class="docEditLink docAdminFormSubmit" name="38" href="#"

问题 I understand that the right way to sort an NSDictionary is to create an array from the keys, sort the array, and then enumerate through the array and operate on the NSDictionary from there. My question is, for an NSDictionary *dict, with keys and values of strings, Why is this alphabetical: NSLog(@"%@", dict); But this is not: for (NSString *w in dict) { NSLog(@"%@", w); } Seems odd... am I doing something wrong? Thanks in advance. 回答1: That's not "in memory" -- %@ causes a message to be

问题 I have a custom post type of "staff". I need to get this to display the staff alphabetically by last name on the page. I know a work around would be to use custom meta boxes and break up first and last names into two fields but I'm trying to avoid that as that seems very hackish and not as clean as just using the title field. I have a shortcode working that will show the custom post type with the staff "type" taxonomy attribute requested. Here is an example: [staff type="local"] I can't just

问题 I have to write a program that reads a list of dictionary words from a file. Subsequently, the characters of each word are put into alphabetical order and stored in the original array. (For example: Batman would become aabmnt). Now, here is what I've done so far: public static String[] alphabeticalOrder(String[] s) { // // Sort each individual string element by alphabetical order // for (int i = 0; i < s.length; i++) { String wordSt = s[i]; char[] word = wordSt.toCharArray(); Arrays.sort(word

问题 I have following data contract: namespace Wcf.Contracts.Data { [DataContract] public class Presence { [DataMember] public int Id { get; set; } [DataMember] public DateTime? From { get; set; } [DataMember] public DateTime? To { get; set; } [DataMember] public TimeSpan? BreakPeriod { get; set; } } } Serializing an instance of Presence to XML and deserializing the same XML back to an instance of Presence works well. But deserializing a string variable which represents a serialized Presence
