[ad_1] I’m amazed this program works. There are sections of code that I don’t understand, for example: STARTB:for (i = 0; i < ns; i++) { if (numholder[i] == “(“) { temp_i = i; i2 = i; } if (numholder[i] == “)”) { temp_i = i – temp_i; } } The variables temp_i and i2 … Read more
[ad_1] Look at your loop here: for(int i=0; i<3*n; i++) { all[j].h = b[i].h; all[j].w = min(b[i].w,b[i].l); all[j].l = max(b[i].w, b[i].l); j++; // increment all[j].h = b[i].l; all[j].w = min(b[i].w,b[i].h); all[j].l = max(b[i].w, b[i].h); j++; // increment again all[j].h = b[i].w; all[j].w = min(b[i].l,b[i].h); all[j].l = max(b[i].l, b[i].h); j++; // increment once again } Look … Read more
[ad_1] You passed username from jQuery with username: $(‘#userId’).val() not userId Try following with $this->input->post(‘username’) $username = strtolower(trim($this->input->post(‘username’))); Or change posted data index from jQuery: username to userId userId: $(‘#userId’).val() 0 [ad_2] solved Check Username or Password Availability Using AJAX on Codeigniter
[ad_1] GNU C compiler has a __builtin_expect to tell the optimizer the most probable outcome of a value. It is not standard C though. You can #define macros to wrap around it and conditionally switch which definition to use, based on the compiler. Linux kernel uses it this way (include/linux/compiler.h): #define likely(x) __builtin_expect(!!(x), 1) #define … Read more

[ad_1] So the question is how to reorder your columns in a custom way. For example you have the following DF and you want to reorder your columns in the following way (indices): 5, 3, rest… DF In [82]: df Out[82]: A B C D E F G 0 1 0 0.5 5 1 7 … Read more
[ad_1] Indeed, you can get the date from a Calendar object: Calendar cal = new GregorianCalendar() Date d; cal.add(Calendar.DATE, 3); d = cal.getTime(); [ad_2] solved How to compute calendar date?
[ad_1] You can achieve that in single query but you need to have some foreign key in other tables. Here check the code below. SELECT b.*, ba.*, bs.* FROM tbl_books as b FULL OUTER JOIN tbl_books_author as ba ON ba.book_id=b.id FULL OUTER JOIN tbl_books_subject as bs ON bs.book_id=b.id WHERE b.title LIKE ‘law’ OR ba.author LIKE … Read more

[ad_1] You are right, all values of deck are 0 at the beginning and the loop works because the do{}while(condition); is executing at least once before checking condition. The loop is looking here for the first uninitialized card. Duplicate output is just what the loop is currently checking, it finds an initialized card so it … Read more
[ad_1] A background (hosted) service is a completely different service, using its own thread to do its job. You can’t have your controller “run” something on that service, you have to tell it what to do, and have it do it. The Background tasks with hosted services section in the docs shows two different ways … Read more
[ad_1] With data.table, we can specify the .SDcols to select the ‘DR’ columns or ‘date_cols’ and assign back the output to those, then instead of using rowwise matching, use a row/column indexing to extract the values to create the ‘Result’ library(data.table) # get the column names that starts with DR dr_names <- grep(“^DR”, names(df1), value … Read more
[ad_1] This is called string interpolation. It’s not a mystery, or a secret; there’s an entire section of the PHP manual dedicated to explaining it. C has printf that does a very similar thing: const unsigned int MAX_SIZE = 255; char variable[MAX_SIZE]; snprintf(variable, MAX_SIZE-1, “Var1 has %d value. Var 2 has %d value.”, var1, var2); … Read more
[ad_1] The user asked for something simple, so I gave him something simple. $input = “[link=http://www.google.com]test[/link]”; $replacement = preg_replace(‘/\[link=(.*?)\](.*?)\[\/link\]/’, ‘<a href=”https://stackoverflow.com/questions/10458103/”>$2</a>’, $input); Where /\[link=(.*?)\](.*?)\[\/link\]/ is the regex, <a href=”https://stackoverflow.com/questions/10458103/”>$2</a> is the format, $input is the input/data, and $replacement is the return. 1 [ad_2] solved How to make PHP BB Codes with RegExp?
