Java code for arranging blocks in rectangular area -

-

I want to arrange equal size blocks in a rectangular area such as

Enter image details here

should be number of input blocks and output should be (n1, n2, N3 ...) where n1 is the number of blocks 1 and so on ....

For example, for the above image (2,3,2) will be for input 7.

Is there some library to achieve this? I want the hurdle to arrange at least rows with each line of the same width. I also want that there should not be more than 4 images in any rows.

With the given information, this is happening for example to be a custom job if I Only 7 blocks were given that you have mentioned that I can end with (2,3,2) like you did (2,2,3) or (3,2,2) or (4,2) , 1), etc.

With a mathematically well-formed solution, you want to make it more compelling. As the following rows do not have as many rows, the rows are added in the following sequence, new rows can not be inserted between existing rows etc.

It is possible to write such algorithms from scratch, but you need to interrupt the probes as much as you describe, the more it is to work for it.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
