See the Wiki for more docs, and Google Groups goki-gi emailing list. The Tree is one of the most flexible, widely-used data structures in programming, including the DOM structure at the core of a web browser, scene graphs for 3D and 2D graphics systems, JSON, XML, SVG, filesystems, programs themselves, etc. This is because trees can capture most relevant forms of structure (hierarchical groupings, categories, relationships, etc) and are most powerful when they are fully generative -- arbitrary new types can be inserted flexibly. GoKi provides a general-purpose tree container type, that can support all of these applications, by embedding and extending the Node struct type that implements the Ki (Ki = Tree in Japanese) interface. Unlike many cases in Go, the need to be able to arbitrarily extend the type space of nodes in the tree within a consistent API, means that the more traditional object-oriented model works best here, with a single common base type, and derived types that handle diverse cases (e.g., different types of widgets in a GUI). GoKi stores a Ki interface of each node, enabling correct virtual function calling on these derived types. A virtue of using an appropriate data representation is that some important operations can be performed particularly concisely and efficiently when they are naturally supported by the data structure. For example, matrices and vectors as supported by numpy or MATLAB provide a concise high-level language for expressing many algorithms. For trees, GoKi leverages the tree structure for automatically computing the appropriate extent of a scenegraph that needs to be updated, with an arbitrary sequence of individual operations, by propagating updating flags through the tree, and tracking the "high water mark" (see UpdateStart / End). This makes the GoGi GUI efficient in terms of what needs to be redrawn, while keeping the code local and simple.

QUESTION
How do I print only 1 copy of data? I am a complete beginner. This is Python code I did for Add data.
This is my current output:
...ANSWER
Answered 2021-Jun-13 at 02:32For each entry in zip(name, age, grade), you have another nested loop (for w). This causes the program to print multiple rows per entry. One way to solve it is to include w inside the zip; i.e., replacing

These two are definitions of INPUT and KEYBDINPUT.
...ANSWER
Answered 2021-Jun-11 at 03:14The problem is not 0. The problem is that you need to initialize a Controllable, Knowable value. You can even use memset(inputs, 1,sizeof(inputs)); which I tested.

QUESTION
I'm hoping someone can help me out. I have created a table and have multiple Tabs. Each Tab has different data inside the table. Each table row has a column with a number of votes and I want to sort the rows automatically with the columns that have more votes at the top.
This is my HTML code:
...ANSWER
Answered 2021-Jun-03 at 03:04Having separate arrays for each tab(comedy and horror) worked for me, so you just create a second array and duplicate the javascript functions, using more specific JS selectors.
QUESTION
Is there a possibility to toggleText() for each element of the array separately?
Right now, when clicked, the values are changed for every single element at the same time and I'd like to go over them one by one as they're clicked.

QUESTION
When I am running buildindex in my Websphere application, I have this error in buildindex log:
...ANSWER
Answered 2021-May-17 at 12:36Thanks to the comment of user @mao, I have followed this link
The failing table first must be identified. Enable more detailed tracing for di-preprocess:
Navigate to :
WC_installdir/instances/instance_name/xml/config/dataimport
and open the logging.properties file. Find all instances of INFO and change it to FINEST. Optionally increase the size of the log file and the number of historical log files while editing this file.
Thanks to this suggestion, I had re-run the buildindex process, and found that solr was wrongly grouping fields from original table, thus generating a too long field for the destination, and generating the error.
QUESTION
I'm aware that this has been an issue many times. However, I don't succeed in converting my xml properly.
This is a data extract of my data. There are several thousand more cases.
...ANSWER
Answered 2021-May-14 at 16:32Here is a solution using the xml2 package. The strategy is to find the reported persons nodes and the parse out all of the subnodes. There are few duplicated node names and I attempted to reduce the number of conflicts, see the comments for more details. You may have to use the node's paths as the dataframe' column names.
