logic

问题 I want to calculate how much queries are executed when i request a page in asp.net mvc. Difficults in page logic: sum queries are executed in main controller action, but others - in widget controller actions, which are called by Html.ActionLink in master page. I wrote base class for all controllers in which i'm encapsulate query called function to increase queries counter - static variable. On page loading it work nice, all queries are counted, but when i requested second page my static

问题 I have 2 tables...they are basically the same except for the column name in one of them because they deal with 2 different names, though.. the data I want is in columns that have the same name. Pretty much what I want to do... is .they also need to be distinct so I don't count duplicates... I can get them as separate tables... but I can't get them together.. I need them in 1 column because of how it is sent to the C3 code page and how it reads it... the structure has already been previously

问题 I have this line of code: convert 1234_Page_1_....png 1234_Page_2_....png output.pdf This merges those particular pngs to a single pdf (using ImageMagick). I have a bunch of files in this format. I would like to perform this merging/converting-to-pdf action on files that have the same number before the " Page ". Sometimes there are more than two pages to convert. I would like to have this done in a perl script that I can run on Windows. Thanks in advance, Jake 回答1: If you wanted to call

问题 I have a dataset containing "facts" recognizable to prolog, i.e.: 'be'('mr jiang', 'representative of china'). 'support'('the establishment of the sar', 'mr jiang'). 'be more than'('# distinguished guests', 'the principal representatives'). 'end with'('the playing of the british national anthem', 'hong kong'). 'follow at'('the stroke of midnight', 'this'). 'take part in'('the ceremony', 'both countries'). 'start at about'('# pm', 'the ceremony'). 'end about'('# am', 'the ceremony'). I want

问题 I'm working on solving a logic puzzle using prolog for school. Here's the clues: Brown, Clark, Jones and Smith are 4 substantial citizens who serve their community as achitect, banker, doctor and lawyer, though not necessarily respectively. Brown, who is more conservative than Jones but more liberal than Smith, is a better golfer than the men who are younger than he is and has a larger income than the men who are older than Clark. The banker, who earns more than the architect, is neither the

问题 I'm an entry level programmer and I usually work on javascript. I'm trying to improve my programming skills, and started working on SPOJ problems. I'm very new to Online programming. Please have a look at this question Input The first line contains integer t, the number of test cases. Integers K are given in the next t lines. Output For each K, output the smallest palindrome larger than K. Below is my implementation. It is exceeding the given time limit to execute. What could be a better

问题 I've been pulling my hair out with this all day, please forgive the short description, I just need to validate my sanity!! As the title says, I'm trying to create two or three different single-product layouts within woocommerce. The minimum is trying to achieve would be to have multiple single-product folders each with their own name and configurations. No matter which way I try to override the single-product.php and make this file use logic to check for the product_cat and give out templates

问题 I am writing a small hangman game in scheme and am getting a very weird issue that almost seems like a language specific one. In my game I have a variable that holds the number of mistakes allowed and on each recursive call of my game loop, I "let" the value to a new one if it needs to be changed. Here is some code to help visualize how I run the game loop. guessed_list - a list of string characters containing old guesses and one new guess (ex. '("a" "x" "b") where "a" is the new guess) game

问题 I'm pretty new to VHDL (and digital circuits in general), and I'm trying to implement a counter of two digits using BCD style blocks. External to this circuit there is going to be buttons, which when pressed, will bump the digit of interest up by one (much like an alarm clock would). This is an asynchronous action, and will occur when in some form of edit mode (externally enforced). The code I have written works fine without the "elsif rising_edge(digitUp1) then" and "elsif rising_edge
