i understand in modulus 17/12 = 5 . why 4+17 % 2-1 value 4 , , (4+17) % 2-1 value 0 ? operator precedence. % evaluated first, so 4 + 17 % 2 - 1 is equivalent to 4 + (17 % 2) - 1 17%2 == 1 yields 4+1-1 equals 4 when place brackets there, change order of evaluation: (4+17) % 2 - 1 is equivalent to 21 % 2 - 1 which again, because of % having higher precendence - , yields 1 - 1 which 0

i trying move project using mysql database 1 uses sql server 2008, select working in mysql no longer working in sql server preparedstatement statement = connection .preparestatement("select u.user_firstname,u.user_lastname user_details u, login l l.username=? , l.login_user = u.user_id"); statement.setstring(1, username); resultset resultset = (resultset) statement.executequery(); it gives me empty resultset when there values corresponding username, when run query using sql server management studio - query works properly i.e. gives non-zero rows, there sql server specific change need ? don't see wrong here, i'd @ how connection object. perhaps database url, pointing wrong schema -- perhaps default one, not database.

this question has answer here: parsing html in python - lxml or beautifulsoup? of these better kinds of purposes? 7 answers i working on project involve parsing html. after searching around, found 2 probable options: beautifulsoup , lxml.html is there reason prefer 1 on other? have used lxml xml time , feel more comfortable it, beautifulsoup seems common. i know should use 1 works me, looking personal experiences both. the simple answer, imo, if trust source well-formed, go lxml solution. otherwise, beautifulsoup way. edit: this answer 3 years old now; it's worth noting, jonathan vanasco in comments, beautifulsoup4 supports using lxml internal parser, can use advanced features , interface of beautifulsoup without of performance hit, if wish (although still reach straight lxml myself -- perhaps it's force of habit :)).

not quite sure how ask :) need have forms online people can fill out, registration form etc. submit , emailed me , have stored in database. there way files pdfs? can have editable pdf form online? thank you. can have editable pdf form online? not -- can have normal form (html served on http), , in server-side method accepts post requests, validate user-supplied data, , if fine generate pdf on fly , return query's result, email it, store it, whatever. details depend on yr server-side language (e.g., if python, you'd use reportlabs' popular pdf-writing package -- there many server-side languages , i'm not know best solution own preferred one, statistically speaking;-). general concept isn't different in each server-side case, , hope i've summarized adequately in previous paragraph;-).

dont know whether duplicate, interview question asked me. given array of random numbers , -1 placed inbetween, have compact array meaning -1s replaced , final output should last valid index fresh array. example. input: 3 4 -1 -1 -1 5 8 -1 8 output: 3 4 5 8 8 5 8 -1 8 , last valid index 4 input: -1 -1 -1 -1 -1 2 output: 2 -1 -1 -1 -1 2 , last valid index 0 input: -1 -1 -1 3 3 3 output: 3 3 3 3 3 3 , last valid index 2 you should not swap values last valid index along array enough decipher not -1 values. int k=0 i=0; i<len; i++ if arr[i]!=-1 arr[k]=arr[i] k++ end if return k-1
