I recently pointed a student doing work experience to an article about dumping a multiplication table to the console. It used a nested for loop and multiplied the step value of each.
This looked like a .NET 2.0 approach. I was wondering, with the use of Linq and extension methods,for example, how many lines of code it would take to achieve the same result.
Is the stackoverflow community up to the challenge?
The challenge:
In a console application, write code to generate a table like this example:
01 02 03 04 05 06 07 08 09
02 04 06 08 10 12 14 16 18
03 06 09 12 15 18 21 24 27
04 08 12 16 20 24 28 32 36
05 10 15 20 25 30 35 40 45
06 12 18 24 30 36 42 48 54
07 14 21 28 35 42 49 56 63
08 16 24 32 40 48 56 64 72
09 18 27 36 45 54 63 72 81
As this turned into a language-agnostic code-golf battle, I'll go with the communities decision about which is the best solution for the accepted answer.
There's been alot of talk about the spec and the format that the table should be in, I purposefully added the 00 format but the double new-line was originally only there because I didn't know how to format the text when creating the post!

This is only 2 lines. It uses lambdas not extension methods
var nums = new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
nums.ForEach(n => { nums.ForEach(n2 => Console.Write((n * n2).ToString("00 "))); Console.WriteLine(); });
and of course it could be done in one long unreadable line
new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9 }.ForEach(n => { new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9 }.ForEach(n2 => Console.Write((n * n2).ToString("00 "))); Console.WriteLine(); });
all of this is assuming you consider a labmda one line?

J's "table" operator (/) equals the K "each-left each-right" (/:\:) idiom. We don't have J's extremely handy "reflexive" operator (~) in K, so we have to pass a as both left and right argument.

Not really a one-liner, but the shortest linq i can think of:
var r = Enumerable.Range(1, 9);
foreach (var z in r.Select(n => r.Select(m => n * m)).Select(a => a.Select(b => b.ToString("00 "))))
{
foreach (var q in z)
Console.Write(q);
Console.WriteLine();
}
In response to combining this and SRuly's answer
Enumberable.Range(1,9).ToList.ForEach(n => Enumberable.Range(1,9).ToList.ForEach(n2 => Console.Write((n * n2).ToString("00 "))); Console.WriteLine(); });

This resolves the complaint about the second parameter of main :)

Based on dreamlax's 97 char answer. His current answer somewhat resembles this one now :)
Compiles ok with gcc, and main(x,y) is fair game for golf i reckon
#define f(i){for(i=0;i++<9;)
main(x,y)f(x)f(y)printf("%.2d ",x*y);puts("");}}

Scala - 77 59 58 chars
print(1 to 9 map(p=>1 to 9 map(q=>"%02d "format(p*q))mkString)mkString("\n"))
Sorry, I had to do this, the Scala solution by Malax was way too readable...
[Edit] For comprehension seems to be the better choice:
for(p<-1 to 9;q<-{println;1 to 9})print("%02d "format p*q)
[Edit] A much longer solution, but without multiplication, and much more obfuscated:
val s=(1 to 9).toSeq
(s:\s){(p,q)=>println(q.map("%02d "format _)mkString)
q zip(s)map(t=>t._1+t._2)}
PHP, 62 chars
for(;$x++<9;print"\n",$y=0)while($y++<9)printf("%02d ",$x*$y);
Java - 155 137 chars
Update 1: replaced string building by direct printing. Saved 18 chars.
class M{public static void main(String[]a){for(int x,y=0,z=10;++y<z;System.out.println())for(x=0;++x<z;System.out.printf("%02d ",x*y));}}
More readable format:
class M{
public static void main(String[]a){
for(int x,y=0,z=10;++y<z;System.out.println())
for(x=0;++x<z;System.out.printf("%02d ",x*y));
}
}
Another attempt using C#/Linq with GroupJoin:
Console.Write(
String.Join(
Environment.NewLine,
Enumerable.Range(1, 9)
.GroupJoin(Enumerable.Range(1, 9), y => 0, x => 0, (y, xx) => String.Join(" ", xx.Select(x => x * y)))
.ToArray()));
Ruby — 47 chars
puts (a=1..9).map{|i|a.map{|j|"%2d"%(j*i)}*" "}
Output
1 2 3 4 5 6 7 8 9
2 4 6 8 10 12 14 16 18
3 6 9 12 15 18 21 24 27
4 8 12 16 20 24 28 32 36

6 12 18 24 30 36 42 48 54
7 14 21 28 35 42 49 56 63
8 16 24 32 40 48 56 64 72
9 18 27 36 45 54 63 72 81
(If we ignore spacing, it becomes 39: puts (a=1..9).map{|i|a.map{|j|j*i}*" "} And anyway, I feel like there's a bit of room for improvement with the wordy map stuff.)

I have the following challenge so far I know how to use the Reduce Method to sum all values in one dim array.
var sum = array.reduce((accumulator, currentValue) => {
return accumulator + currentValue; });
But how can I use this Method on an 2d array? For example I want to sum all items from the 5. column in the 2d Array.
Not complete sure if this is want you're looking for
function sumfive() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Sheet0');
const [h, ...v] = sh.getDataRange().getValues();
let sum = v.reduce((a, r) => {
let row = 0;
r.forEach((c, i) => {
if (i > 4) { row += Number(c); }
});
a.sum += row;
return a;
}, { sum: 0, getSum: function () { return this.sum; } }).getSum();
Logger.log(sum);
}

when I run the below query it gives 14 rows(duplicate row returning).expected out put row is 6.. Please refer below output tables..
select prm.prm_voucher_no,prm.project_id,prm.status_id,prd.requested_quantity,prd.item_id,pom.pom_voucher_no,pom.supplier_id,pod.rate,pod.approved_quantity
from purchase_request_master prm
left join purchase_request_details prd on prd.prm_voucher_no=prm.prm_voucher_no
left join purchase_order_master pom on prm.prm_voucher_no=pom.request_id
left join purchase_order_details pod on pom.pom_voucher_no=pod.pom_voucher_no
where prm.project_id=46 and ( EXTRACT(MONTH FROM prm.request_Date)=6) and (EXTRACT(YEAR FROM prm.request_Date)=2016)
group by prm.voucher_no,prm.project_id,prm.status_id,prd.requested_quantity,prd.item_id,pom.voucher_no,pom.supplier_id,pod.rate,pod.approved_quantity
order by prm.voucher_no
i tried inner join,distinct,distinct least,group by,temporary table,with clause all these method.. but no use every this gives duplicate row
How to solve this problem..

I think the problem is in your data model itself. Ideally, you would have a line_number field in both of your "detail" tables, and this would be used in the join:
create table purchase_request_details (
prm_voucher_no integer,
prm_voucher_line integer, // Add this
item_id integer,
request_quantity
)
create table purchase_order_details (
pom_voucher_no integer,
pom_voucher_line integer, // and this
approved_quantity integer,
rate integer
)
And then this query would give you the results you seek:
select
prm.prm_voucher_no,prm.project_id,prm.status_id,prd.request_quantity,
prd.item_id,pom.pom_voucher_no,pom.supplier_id,pod.rate,pod.approved_quantity
from
purchase_request_master prm
left join purchase_request_details prd on
prd.prm_voucher_no=prm.prm_voucher_no
left join purchase_order_master pom on
prm.prm_voucher_no=pom.prm_request_id
left join purchase_order_details pod on
pom.pom_voucher_no=pod.pom_voucher_no and
prd.prm_voucher_line = pod.pom_voucher_line // This is the key
where
prm.project_id=46 and
EXTRACT(MONTH FROM prm.request_Date) = 6 and
EXTRACT(YEAR FROM prm.request_Date) = 2016
order by prm.prm_voucher_no
If you have no ability to control the data model, then I think the best you can do is artificially add a line number. I don't recommend this at all, as you are presupposing a lot of things, most notably that the order of records in the one table automatically correlates to the order of records in the other -- and I'm betting that's far from a guarantee.
Adding a line number would be done using the row_number() analytic, and PostgreSQL has that but MySQL does not... you have both tags in your question. Which DBMS are you using?
If you can't add line numbers, can you add item_id to your purchase_order_details table? This would likely handle your issue, unless you can have the same item on multiple lines within a purchase request/order.
In the data you have above, a join on the requested quantity (prd.request_quantity = pod.approved_quantity) fixes your issue, but I am highly confident that this would burn you when you started running it against real data.
Please i need help to calculate moving average in SSRS. see example from excel bellow. i have search net and looked at other forum without success.
the moving average is something like Avg(A1:A3),Avg(A2:A4),Avg(A3:A5)etc
Count of ID BAND

Year Month <15 15-20 >20 Total

I'm trying to sort an array of "tile" objects in as3 by the value of its "realY" property.
This is my code:
tiles.sortOn("realY", Array.DESCENDING);
tiles.reverse();
for each(var t:Tile in tiles)
{
trace(t.nearness);
}
This is the output:

As you can see, there are some random small numbers at the end. Why is this happening?
Thanks
Try using your sortOn like this:
tiles.sortOn("realY", Array.NUMERIC | Array.DESCENDING);
By default Flash is sorting in alphabetical order. Check the documentation for more info.
Besides that, you're tracing the nearness property, not the realY property you sorted. So maybe that's a problem too.
