I'm completely new to Python and while trying various random bits and pieces I've struck upon a problem that I believe I've "solved", but the code doesn't feel right - I strongly suspect there is going to be a better way to get the desired result. FYI - I'm using whatever the latest version of Python 3 is, on Windows. Problem definitio...
In Hadoop you can use the secondary-sort mechanism to sort the values before they are sent to the reducer. The way this is done in Hadoop is that you add the value to sort by to the key and then have some custom group and key compare methods that hook into the sorting system. So you'll need to have a key that consists essentially of bo...
I just found this irregularitry in a query i made, why does the result differ when using inner and left joins? for one, the result is ordered both in the temporary hit table and in the final query? I made a little example to show the problem: # cleanup drop temporary table if exists ids; drop temporary table if exists arts; # create t...
I have an array as following and I want to order that array by the value of the key "attack". First keys of the arrays (15, 13, 18) are ID of some certain item from database, so I don't want these keys to be changed when the array is sorted. Any help would be greatly appreciated. This is the array: $data = array('15' => array('attack' ...
Is it possible to sort the output of the Format-List cmdlet by property name? Suppose that I have an object $x with two properties "A" and "B", and when I run Format-List with it I get (PS) > $x | Format-List B : value b A : value a I would like to have (PS) > $x | Format-List A : value a B : value b NOTE: I should have specified ...
Hello. First off I am new to this site and it is a big help, so thanks in advance for the input. I am trying to shift a subset of array values after comparing them, like asort. Here is what I have: $array[name] = "name"; $array[date] = "date"; $array[item1] = 7; $array[item2] = 16; $array[item3] = 3; $array[item4] = 16; $array[item...
I came across the following question. Given an array of n elements and an integer k where k < n. Elements {a0...ak} and {ak+1...an} are already sorted. Give an algorithm to sort in O(n) time and O(1) space. It does not seem to me like it can be done in O(n) time and O(1) space. The problem really seems to be asking how to do the merge ...
Hey, I'm trying to implement the merge function from merge sort in Lua. I know the algorithm pretty well, but I'm new to Lua. I keep getting a "bad argument #1 to 'insert' (table expected, got nil)" I believe the error is pointing at my recursive call. I can't figure it out and I have a feeling it's something pretty trivial. I just n...
I'm currently playing with implementing various sorting algorithms in Java, mostly for fun, but I'm struggling with how to do it 'right'. That is, I want the user to be able to call the sorting algorithm of choice on anything that is comparable - ints, longs, Strings, booleans (actually, are these comparable in Java?), their own classes;...
I have 2 tables in a mysql database : users and pets. In the users table there is a field that contains a semicolon separated list of the pets that a user has (pet_ids = 1;2;3;4;). These ids correspond to unique ids (keys) in the pets table which contain the pet name (1 = rex, 2 = goldie, 3 = squeak, 4 = bubble). I want to present a lis...
Dear all, I'd like to sort a categorical variable my own way. I have grouped my dataset into categories like "1-5","6-10","11-20" .... ">251" and so forth. If plot the variables or display them in a table the sequence of the legend respectively the sequence in the label is "messed up". This is not surprising since R does not know that...
Hi I have document with fields like (title, content, datetime) I want to sort the results with the following formula 1) title boosts 2.5 2) content boost 1.5 3) IMPORTANT (boost those documents that is newer means datetime field is near today date) boost 3 how can I write a query considering the above criteria what should I do for #3...
In my current solution, I am converting a DateTime value, "Time" in my database using CONVERT so it displays in a ##:##AM/PM format, and I realize that CONVERT just takes whatever datatype and turns it into a VarChar, or a String once its in C#. This is making my sort work incorrectly in my Gridview. I am sorting the columns in my DataSe...
