PHP Vertical Alphabet Using FOR Cycle

由 泄露秘密 提交于 2019-12-11 03:38:32
问题 I'm trying to do a script in PHP which will generate a table with vertical alphabet in it. It will simply echo letters from A to Z and when it comes to Z, it will reset and begin from A again. I have a problem with this because I only can repeat this twice, then all cells have some unwanted signs in them. I'm echo-ing the letter using their ASCII html codes, where the A sign is &#65 and the Z sign is &#90. Here is the code I have until now, thanks for help. <!DOCTYPE html> <html> <head> <meta

问题 Given the alphabet {a, b} we define N a (w) as the number of occurrences of a in the word w and similarly for N b (w) . Show that the following set over {a, b} is regular. A = {xy | N a (x) = N b (y)} I'm having a hard time figuring out where to start solving this problem. Any information would be greatly appreciated. 回答1: Yes it is regular language! Any string consists if a and b belongs the language A = {xy | N a (x) = N b (y)} . Example: Suppose string is: w = aaaab we can divide this

UITableView - Alphabet

问题 Here is the improvement that I wish to add to my UITableView with alphabet: If there are no results in my table that don't start with one of the letters of the alphabet, I don't want to see this titleForHeaderInSection in my UITableView. And I don't find the way to do that. You can see my current implementation and an image as example (http://blog.joefusco.name/wp-content/uploads/2010/10/indexed-table.jpg): facilitiesViewController.h: @interface FacilitiesViewController :

问题 I did look up answers, and they are good for the standard alphabet. but I have a different situation than that. so, I am programming in Java. I am writing a certain program. this program has at some place some list of string items. I would like to sort those string items according to the alphabet. if I would sort it by English alphabet, it would be easy since usually all code pages are compatible with American standard code for information interchange (ASCII), and they have all letters of

How do I iterate through the alphabet?

问题 In Python, could I simply ++ a char? What is an efficient way of doing this? I want to iterate through URLs that have the www.website.com/term/#, www.website.com/term/a, www.website.com/term/b, www.website.com/term/c, www.website.com/term/d ... www.website.com/term/z format. 回答1: You can use string.ascii_lowercase which is simply a convenience string of lowercase letters, >>> from string import ascii_lowercase >>> for c in ascii_lowercase: ... # append to your url 回答2: In addition to string

Is there an easy way to programmatically get the alphabet?

问题 I want an NSArray/NSMutableArray containing all the letters of the alphabet. There must be a quick and easy way, better than typing them all out. For example in PHP: foreach(range('A','Z') as $i) $alphabet[]=$i; 回答1: There's no quicker way than typing them all out, unless you cut and paste my handy reference from below! "abcdefghijklmnopqrstuvwxyz" For the sake of it, here's a longer way. for (char a = 'a'; a <= 'z'; a++) { [myArray addObject:[NSString stringWithFormat:@"%c", a]]; } 回答2: The

Strings to Integers

由 a 夏天 提交于 2019-12-04 06:08:20
问题 Say you have the string "Hi" . How do you get a value of 8 , 9 ( "H" is the 8th letter of the alphabet, and "i" is the 9th letter). Then say, add 1 to those integers and make it 9 , 10 which can then be made back into the string "Ij" ? Is it possible? 回答1: use ord to get the ASCII index, and chr to bring it back. 'Hi'.chars.map{|x| (x.ord+1).chr}.join 回答2: Note Cary Swoveland had already given a same answer in a comment to the question. It is impossible to do that through the numbers 8 and 9

Arranging by Alphabetical Order

由 时光总嘲笑我的痴心妄想 提交于 2019-12-04 05:10:42
问题 I'm new to Java and I'm trying to arrange an arrayList of terms in alphabetical order. (A term is defined as a char and an int) (e.g. {Term('Z',4),Term('C',3),Term('Q',2) ...} ) My code is as follows: public Term nextElement() { Term max = terms.get(0); char maxtest = max.getElement(); for (int i = 1; i < terms.size(); i++){ Term tester = terms.get(i); char maxtest2 = tester.getElement(); if (maxtest2 > maxtest) { tester = max; } } return max; } Why isn't this working? and how do I accomplish
