algorithm - Small questions on data structure -

-

I want to find the parents of a node with Kruskal's algorithm. My program works just fine, but I think I've heard of a method for improving the speed of the algorithm and connecting to the parent node by reconfiguring the paper while searching for the parent node. I am pretty sure that I have heard something about it, perhaps in a lecture. Can someone refresh my memory?

Moreover, while looking at the minimum and maximum value of a certain segment of an array, looking at the many arrays, what is the name of the tree that can be calculated in the O (log n) By creating a binary tree with a minimum / maximum value of each array, the minimum / maximum value from the array?

Regarding your second question: I think you are talking about one. You can get a heap in the minimum or maximum O (1) and delete it in o (log n).

Although there are some sophisticated data structures, which are meant to handle entire lists (i.e. they are not specifically designed for minimum / maximum access). (amortized O (log n)) These minimum at least and help maximize use

    In relation to your first question: one is used to calculate but since you If you mention the "parent node", I think that your considered structure is already a tree but if the structure is already a tree, Cruscle algorithm only returns the tree. Can you possibly understand what it means by "parent node"

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
