so there user directory space. each user gets own space , can upload .gif, jpg, png, , mp4 files them. the user can create , manage own files in many directories or sub-directories wish. i have no idea how need end result have no example code. need end result follows: foreach ($file $file) { $data[] = array('type' => 'image', 'path' => $file["path"], 'name' => $file[name], 'time' => $file["update_time"]); } how details directories keeping in mind have no idea structure after base directory. also, need exclude directories , files begin . (such .htaccess, there others) here go. usa recursive function iterate on each directory. if directory recursion, otherwise , store data: $directorytoscan = './'; $results = []; $tree = getdirenties($directorytoscan, $results); var_dump($tree); function getdirenties($directory, &$results) { $entries = scandir($directory);

when install jdk, after installation of jdk prompts let choose location install jre of save version. but, when jdk installation done, can see jre folder inside jdk folder. example, if install jdk in: c:\program files\java\jdk8 we can see: c:\program files\java\jdk8\jre and if choose save jre at: c:\program files\java\jre8 we can find folder contains (nearly) same content jre inside jdk folder. difference between these two? as oracle installation manual suggests in section " private versus public jre ": private versus public jre installing jdk installs private jre , optionally public copy. private jre required run tools included jdk. has no registry settings , contained entirely in jre directory (typically @ c:\program files\jdk1.8.0\jre ) location known jdk. on other hand, public jre can used other java applications, contained outside jdk (typically @ c:\program files\java\jre1.8.0 ), registered windows registry (at hkey_local_machine\sof

edit: never mind, being stupid. i came across code recursion on smaller , smaller substrings, here's essence plus testing stuff: def f(s): if len(s) == 2**20: input('check memory usage again') else: f(s[1:]) input('check memory usage, press enter') f('a' * (2**20 + 500)) before call, python process takes 9 mb (as checked windows task manager). after 500 levels ~1mb strings, it's @ 513 mb. no surprise, each call level still holding on string in s variable. but tried fix replacing reference string reference new string , still goes 513 mb: def f(s): if len(s) == 2**20: input('check memory usage again') else: s = s[1:] f(s) input('check memory usage, press enter') f('a' * (2**20 + 500)) why doesn't let go off memory? strings smaller, later strings fit space of earlier strings. there hidden additional references strings somewhere or going on? i had expecte

i've been doing interview prep questions , question i've had trouble i'm unsure how implement solution. here's setup. you're given 8x8 grid of letters , list of words, , must return longest word in list can formed starting @ letter on grid , moving grid in way knight in chess. example, if had list ["word", "string", "test"] , following grid: y w e z t n u w o p a c q g f t e l z x c v b n m m w f r t o u o n s d f b e j o l z v c t b n m q w e r t s g x z r s then return "test", because can formed starting @ bottom left corner of grid 't', jumping 2 , right 1 'e', jumping down 2 , right 1 's', , left 2 , 1 't', , none of other words can formed on grid. i think you'd use branch , bound algorithm i'm totally lost on how set up. help? i'm trying implement in python. note: letters can repeated in grid, i.e. can jump on same letter many times want. my solution is: eve

for reason method gettwo() inside pollclass won't return 2 undefined . if put return statement outside .foreach() loop value returned however. class poll { constructor(name) { this.name = name; this.nums = [1, 2, 3]; } gettwo() { this.nums.foreach(num => { if (num === 2) return num; }) } } const newpoll = new poll('random name'); console.log(newpoll.gettwo()); // returns undefined, not 2 is issue closure, es 6, or whole other issue? an arrow function still function, , you're returning foreach callback function, not gettwo, have return gettwo function well. it's not quite clear why use loop check in way, concept like gettwo() { var n = 0; this.nums.foreach(num => { if (num === 2) n = num; }) return n; // returns gettwo() }
