listening collections lecture functional programming principles in scala , saw example: scala> val s = "hello world" scala> s.flatmap(c => ("." + c)) // prepend each element period res5: string = .h.e.l.l.o. .w.o.r.l.d then, curious why mr. odersky didn't use map here. but, when tried map, got different result expected. scala> s.map(c => ("." + c)) res8: scala.collection.immutable.indexedseq[string] = vector(.h, .e, .l, .l, .o, ". ", .w, .o, .r, .l, i expected above call return string, since i'm map -ing, i.e. applying function each item in "sequence," , returning new "sequence." however, perform map rather flatmap list[string] : scala> val slist = s.tolist slist: list[char] = list(h, e, l, l, o, , w, o, r, l, d) scala> slist.map(c => "." + c) res9: list[string] = list(.h, .e, .l, .l, .o, ".

i'm working on class has inner classes. these classes public , variable passed on other class declared public also. problem whenever, try access example inner class named public class classx and needing variable public int position . inside inner class classx there method calculating position, , in inner class public class classy , wanted display current value of position whenever tried access position classx null?how happen? by way, aware of using instantiate , using constructor. tried set reset value. here sample code: public class mainclass { public static class subclass1 { public int position,x,y; } public class subclass2 { private subclass1 s; public void methodcalculate() { s = new subclass1(); s.position = s.x + sy; } } public class subclass3 { private subclass1 s; public void displaymethod() {

i working on application using rails 4. in page, have checkbox want store in user session hash. following code: # show.html.erb ... <%= check_box_tag "", "", staytuned_get(some_id), onclick: staytuned_swap(some_id) %> ... # myhelper.rb def staytuned_get(some_id) session["staytuned_#{some_id}"] || false end def staytuned_swap(some_id) session["staytuned_#{some_id}"] != session["staytuned_#{some_id}"] end staytuned_get returns false if "staytuned_#{some_id}" not set or false. otherwise, returns true. staytuned_swap swaps boolean session variable (from true false , vice versa). unfortunately, session["staytuned_#{some_id}"] false, after click , refresh. can solve this, thank you. this not how works in browser. when onclick: staytuned_swap(someid) , calls function, return false (a variable equal ...) , use onclick attribute. want javascript doing ajax on click.

i'm trying make bool isprime function creates list of prime numbers covering user-input integer, linearly search through list , return true if input integer in list. i'm having problem, however, figuring out how make list covers input integer (that is, if user inputs 4, list must have 2,3, , 5). here code have far (i know it's wrong, i've tried doing research can't figure out how this. bool isprime(int n){ int i,tprime=3; list<int>prime; prime.push_back(2); list<int>::iterator it; (it=prime.begin();it!=prime.end();it++){ if (*it<n){ while (i<sqrt(tprime)){ if(n%i!=0){ if(i<sqrt(tprime)) i++; else prime.push_back(tprime); } tprime++; } } } (it=prime.begin();it!=prime.end();it++){ if (*it==n) return true; } return false; } can guys give me hints on how make work? can figure out linear search. you got list

"); scanf("%d", &num_balls); /* ensure atleast 1 ball */ while(num_balls <= 0) { printf("you have drop @ least 1 ball! \n "); printf("how many balls should dropped? "); scanf("%d", &num_balls); } /* return number of balls dropped */ return num_balls;

while programming, many times i've come across following design choice: user creates object , passes other object processes in way in second stage. as example, imagine raytracer. user creates sphere properties , calls raytracer.addtraceable(sphere) . now, there 3 ways can think of doing this. the raytracer becomes responsible of deallocating memory allocated sphere object the user needs deallocate memory allocated sphere object. the raytracer copies sphere object , both user , raytracer deallocate local copy. generally best design choice in such case? there other options besides ones mentioned (not including smart pointers)? ps: i've come across same problem in plain c when using object oriented approach. the consistent use of raii makes moot point. using smart pointer such std::shared_ptr object owned all of pointers , deleted after last pointer destroyed. c doesn't have convenient way express raii idiom.

in erlang can use define macro or .hrl file keep configuration @ 1 place. whats best place in elixir. i couldn't find elegant way of doing it. right doing like:- def get_server_name "test" end am missing something? whether use functions or macros should matter in end, if you're looking "keeping in 1 place" part, i'd suggest putting in own namespace/module defmodule myapp.configuration def server_name "foo" end # or if prefer having on 1 line def host_name, do: "example.com" # complete equivalency, can use macro defmacro other_config "some value" end end and in app, instead of including file, can alias module have short prefix indicate it's configuration, , indicate come elsewhere defmodule myapp.server alias myapp.configuration, as: c end or if want use names directly defmodule myapp.server import myapp.configuration end

i'm supposed smallest , largest number out of sequence of numbers. know method body each method not right. help? public class dataset { private int sum; private int count; private int largest; private int smallest; public dataset() { sum = 0; count = 0; largest = 0; smallest = 0; } public void addvalue(int x) { sum = sum + x; count++; } public int getsum() { return sum; } public double getaverage() { double average = sum/count; return average; } public int getlargest() { int largest = integer.max_value;//not giving right answer, don't know how use return largest; } public int getsmallest() { int smallest = integer.min_value;//not giving right answer, don't know how use return smallest; } } here tester class if needed, although don't think problem lies here. public class datasettester { public static void main(string[] args) { dataset mydata = new dataset(); myd

i having trouble assignment have, after displaying results of coin flip program, typically like: (this c# way) heads tails tails tails etc. i have group them in rows. example, if name group(10, 4), 10 mean total flips of "coin" , 4 how results grouped: heads tails tails tails tails heads tails tails heads heads i'm confused whether in flips() should in groups() along loop manipulate sorting of results? or totally separate? i'm stumped on how begin.. sorry, appreciated! using system; namespace heads_tails { class mainclass { static void main() { (int v = 0; v <= 10; v++) flip (); } static void flip() { int lo, hi, n; random r = new random (); lo = 0; hi = 2; n = r.next(lo, hi); if (n == 1) { console.writeline ("heads"); } else { console.writeline ("tails"); } } } } here's hint

i have 2 member replica set (within sharded cluster), no arbiter. know recommended design have 3 servers (or odd number) right have stick design. the problem when primary down, secondary doesn't elected temporary master (since priority both servers 1 , have no arbiter). is there way automatic failover (slave becomes primary -> primary online -> default primary gets previous state)? thank you! you must have @ least 3 members in replicaset, having 2 members worse having single node (never ever this!!). problem worst think, main problem if secondary goes down, primary demote secondary , go down because have no more primary. don't know why 'have stick configuration', can not solution. the solution create , arbiter , node, lightweight member of replicaset has no actual data , there take part in election new primary if 1 of other members goes down.
