问题 I'm quite new to jQuery, and I've written a simple function to check the strength of a password for each keypress. The idea is that every time a user enters a character, the contents is evaluated to test the strengh of the password they have entered... I'm sure everyone has seen these before. Anyhow, the logic I have used is that no password begins with a value of 1. When a lower-case character is used, the score increments to 2. When a digit is used the score increments by 1 again, same for

问题 I have a logic problem for an iOS app but I don't want to solve it using brute-force. I have a set of integers, the values are not unique: [3,4,1,7,1,2,5,6,3,4........] How can I get a subset from it with these 3 conditions: I can only pick a defined amount of values. The sum of the picked elements are equal to a value. The selection must be random, so if there's more than one solution to the value, it will not always return the same. Thanks in advance! 回答1: This is the subset sum problem, it

问题 I have an existing data set that utilizes an integer to store multiple values; the legacy front end did a simple bitwise check (e.g. in C#: iValues & 16 == 16) to see if a particular value was set. Is it possible to do bitwise operations in XSL, and more explicitly, to do bit level comparisons via masking? The built-in "and" will always result in "true" or "false", but perhaps it's possible via the math operators available? I'm currently using .NET 2.0, which uses XSLT 1.0. 回答1: I haven't

问题 I'm trying to implement the logic in Cypher where, based on a particular condition ( CASE Statement), I would create some nodes and relationships; the code is as below MATCH (g:Game)-[:PLAYER]->(u:User)-[r1:AT]->(b1:Block)-[:NEXT]->(b2:Block) WHERE g.game_id='G222' and u.email_id = 'xyz@example.com' and b1.block_id='16' SET r1.status='Skipped', r1.enddate=20141225 WITH u, b2,b1, g, r1 SET b1.test = CASE b2.fork WHEN 'y' THEN MERGE (u)-[r2:STAGE {startdate:20141225, enddate:'99999999', status:

问题 I've made a nice form, and a big complicated 'add' function for handling it. It starts like this... def add(req): if req.method == 'POST': form = ArticleForm(req.POST) if form.is_valid(): article = form.save(commit=False) article.author = req.user # more processing ... Now I don't really want to duplicate all that functionality in the edit() method, so I figured edit could use the exact same template, and maybe just add an id field to the form so the add function knew what it was editing. But

问题 I want to create a function in C. It will return a random integer in-range of N like:- rand() % N; but the thing is I want to keep track of uniqueness. I don't want the numbers to repeat. but i can also do this by making an array and copying the generated integers in it. like :- array[count] = rand() % N; and check every time if the number generated was already inside it or not. (simply by searching it inside the array[]); this is a simple approach but a correct one. it will take many if's

问题 Anybody have thoughts on generating a row of a truth table with out creating the entire table. For example, a user would enter in a row number and that truth table row is generated. Also, this should be done without creating the table until you get to that row number. Essentially, I want to know if there is an efficient way to calculate a truth row value only based on a the truth table row as an input. Example: Assume 3 variables printTruthTableRow(3) would produce 010 Actually, could I just
