i have implemented queue using 2 stacks , want find top n percent elements in queue. for example: queue takes element in order {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20} top 10% elements means 10% of 20 = 2 hence answer should 19 , 20 there 2 ways can think of sort queue, claculate number of items (x) n% , grab top x elements. selection algorithm . (i came across algorithm , based on idea of quicksort. have copy entire queue array , apply algorithm) is there better way solve this? a queue isn't best data structure that, should not access elements inside (most of queue implementations don't provide access operator) shouldn't sort it. so, if don't need queue due other requirements, suggest use plain array. sorting time consuming process. read/insert queue elements can compute sum. based on known sum, number of elements , percent required, can compute threshold. then, need iterate through elements (if using queue, can extract them 1...

if have multiple children created fork(), , method of communication parent "named pipes", need multiple named pipes? 1 each child? or can make 1 , have parent read that? basically, there else need do? understand if several children write same named pipe @ same time, might cause problem reading whole message single child. there way make sure writes atomic? you can have several writers single pipe. however, communication between fork()ed children , parent, might not need named pipes @ all. named pipes visible in file system , can used communication between processes not parent/child. about atomicity: if write less pipe_buf (no less 512 bytes, 4096 bytes on linux, limits.h), write atomic , there no mixing of messages different writers. if write more pipe_buf, don't rely on writes being atomic. the pipe(7) manual page says that: pipe_buf posix.1-2001 says write(2)s of less pipe_buf bytes must atomic: output data written pipe contiguous s...

i'm new in r , i'm trying figure out how make function faster using sapply, help? x <- c(0.0, 1.0, 2.0, 3.0, 4.0, 5.7) y <- c(10.0, 7.0, 5.5, 4.5, 3.2, na) z <- c(as.data.frame(cbind(x,y)) vcub=function(y, x, z) { vol<-vector() for(i in 1:dim(z)[1]){ if(is.na(y[i])) { vol[i]<-(((pi*y[i-1]^2)/40000)/3)*(x[i]-x[i-1]) }else{ vol[i]<-(((pi*y[i-1]^2) + (pi*y[i]^2))/80000)*(x[i]-x[i-1]) } } return(as.data.frame(vol)) } you can vectorize code replacing if , else statements in loop ifelse statement , using vectorized arithmetic in r: data.frame(vol=ifelse(is.na(y), pi*c(na, head(y, -1)^2)/120000*c(na, diff(x)), pi*(y^2 + c(na, head(y, -1)^2))/80000*c(na, diff(x)))) # vol # 1 na # 2 0.0058512163 # 3 0.0031121402 # 4 0.0019831304 # 5 0.0011973395 # 6 0.0004557404 in general, it's easy vectorize computation when can compute i^th ...

when running script, getting several errors this: warning: cannot modify header information - headers sent ( output started @ /some/file.php:12 ) in /some/file.php on line 23 the lines mentioned in error messages contain header() , setcookie() calls. what reason this? , how fix it? no output before sending headers! functions send/modify http headers must invoked before output made . summary ⇊ otherwise call fails: warning: cannot modify header information - headers sent (output started @ script:line ) some functions modifying http header are: header / header_remove session_start / session_regenerate_id setcookie / setrawcookie output can be: unintentional: whitespace before <?php or after ?> the utf-8 byte order mark specifically previous error messages or notices intentional: print , echo , other functions producing output raw <html> sections prior <?php code. why happen? to understand why hea...

is there way take unknown schema xml file , convert values, tags, etc xml file pojo? looked @ jaxb , seems best way use if know xml schema. basically, want able parse tags xml put each own object maybe through use of arraylist. did not understand jaxb can or there better tool can this, or hard implement? in hope helps understand situation! public static void dumpallnodes( string path ) throws exception { documentbuilder parser = documentbuilderfactory.newinstance().newdocumentbuilder(); document doc = parser.parse(new file(path)); nodelist nodes = doc.getelementsbytagnamens( "*", "*" ); for( int = 0; < nodes.getlength(); i++ ){ node node = nodes.item( ); system.out.println( node.getnodetype() + " " + node.getnodename() ); } } the nodelist nodes contains element nodes, in document order (opening tag). thus, elements contained within elements in list, alike. obtain attributes of node, call nam...
