The code below shows nested while loops, but it's not the very efficient. Suppose I wanted to extend the code to include 100 nested while loops. Is there a better way to accomplish this task? <?php $count = 1; $num = 1; $options=3; while ( $num <=$options ) { echo "(".$num . ") "; $num1 = 1; $options1=3; whil...
I think this might be a pretty simple question, but I haven't been able to figure it out yet. If I've got a 2-dimensional array like so: int[,] = new int[2,3] { {1, 2, 3}, {4, 5, 6} }; What's the best way to iterate through each dimension of the array with a nested foreach statement? ...
I'm trying to process a for loop within a for loop, and just a little wary of the syntax... Will this work? Essentially, I want to run code for every 1,000 records while the count is equal to or less than the $count... Will the syntax below work, or is there a better way? for($x = 0; $x <= 700000; $x++) { for($i = 0; $i <= 1000; $...
I decided to do an image to explain this better, I just want to check my thinking is ok, and that I can reduce total permutations by 75%: ...
I'm making a for loop within a for loop. I'm looping through a list and finding a specific string that contains a regular expression pattern. Once I find the line, I need to search to find the next line of a certain pattern. I need to store both lines to be able to parse out the time for them. I've created a counter to keep track of the...
Given a canvas, let's say 10x10, and given 3 rectangles/squares. Canvas = 10x10 Rectangle 1 = 2x2 Rectangle 2 = 3x3 Rectangle 3 = 2x4 I've created a recursive function that loops every position of every rectangle on the canvas, and it works fine. (I've included the function below incase anyone wants to see it but I don't think it's n...
In using ReSharper recently, it is suggesting I reduce nesting in certain places by inverting if conditions and using the continue statements. nested conditionals: foreach(....) { if(SomeCondition) { //do some things if(SomeOtherNestedCondition) { //do some further things } } } ...
Hi, I have a nested loop2(check2) in loop1(check1) but it seems that nested loop2(check2) only runs once. Both loops contain the same array. This script is used to check for a duplicate id in check1. check1=["0", "0", "0", "1", "1", "2", "3", "4", "5", "100", "4294967294", "9", "11", "6", "200", "7", "201", "811", "202", "204", "3000",...
I'm confused about the complexity of the following (the operation performed inside the inner loop is in constant time): for(int i=0; i<n; i++) for(int j=i; j<n; j++) is this O(n^2) or O(n)? I figure O(n^2). Any ideas? also the following makes me curious: for(int i=0; i<n; i++) for(j=0; j<i; j++) ...
I have an app that does an iteration to create points on a graph over time. While I'm gathering data for each point across the x-axis I also must execute a recursive lookup which effectually means I have a loop inside another loop. This is not scaling too well. I don't see a lot of examples of using a "divide and conquer" solution on it...
I have a function that adds shopping cart data to an array of arrays. The array looks like this: Array ( [0] => Array ( [TypeFlag] => S [qty] => 2 [denom] => 50 [certMessage] => [totalPrice] => 100 ) [1] => Array ( [TypeFlag] => S [qty] => 1 [denom] => 25 [certMessage] => [totalPrice] => 25 ) ) What I need to do is get the total p...
Hi I have a method that returns an array of support tickets. Each support ticket can have many notes so I have a method that returns an array of tickets notes with that ticket id. I want to display the notes alongside the ticket which would mean nesting the get notes inside the foreach loop. foreach($tickets as $ticket){ //display...
$tasks->{t1}{cmdline} = "convert -f %FONT% %1%"; $tasks->{t1}{report} = "Launched as %CMD% by %USER%"; $tid = 't1'; foreach my $parm (keys %{$tasks->{$tid}}) { $tasks->{$tid}{$parm}=~s/%FONT%/$tasks->{$tid}{font}/g; # may evaluate if $parm == 'cmdline'; $tasks->{$tid}{$parm}=~s/%CMD%/$tasks->{$tid}{cmdline}/g; } The code is bad...
I have been trying to optimize the two following nested loops: def startbars(query_name, commodity_name): global h_list nc, s, h_list = [], {}, {} query = """ SELECT wbcode, Year, """+query_name+""" FROM innovotable WHERE commodity='"""+commodity_name+"""' and """+query_name+""" != 'NU...
$teams = array(1, 2, 3, 4, 5, 6, 7, 8); $game1 = array(2, 4, 6, 8); $game2 = array(); if teams[x] is not in game1 then insert into game2 for($i = 0; $i < count($teams); $i++){ for($j = 0; $j < count($game1); $j++){ if($teams[$i] == $game1[$j]){ break; } else { array_push($game2, $teams[$i]);...
Hi, I am trying to output a range of commands with different dates and numbers associated. for each hour eg. Output im trying to do in a loop is: shell.sh filename<number e.g. between 1-24> <date e.g. 20100928> <number e.g. between 1-24> <id> So basically the the above will generate an output done 24 times for each particular day w...
I'm trying to loop round a load of tar files and then move the extracted files into a new folder, inspect them and delete them before moving onto the next tar. Code is below: for i in * do tar -zxvf $i mv *TTF* encoded cd encoded for j in * do echo $j done rm -f *TTF* cd .. done When it gets to the nested loop, ...
Are nested while loops broken in golfscript or do I not know how to use them? I want to iterate Q from 5 to 0, and for each iteration, iterate Z from 10 to 0. The single loops work well separately, and they seem self-contained (not relying on the stack between operations): 5:Q; {"Q:"Q+ p Q} { Q 1- :Q; }while 10:Z;{"Z:"Z+ p Z}{Z 1- :...
I'm rather confused at the moment, could someone explain this one to me? Maybe it's something small I'm oblivious to, but I'm confused as to why this isn't resulting as I expect it to. I have created a samples to show the issue I'm seeing... Sample 1 var dataString = "abc"; document.write(" This is a test ... " + "<br/>") for (i in d...
I've been tasked with helping some accountants solve a common problem they have - given a list of transactions and a total deposit, which transactions are part of the deposit? For example, say I have this list of numbers: 1.00 2.50 3.75 8.00 And I know that my total deposit is 10.50, I can easily see that it's made up of the 8.00 and ...
