So I have this code where I get the values from an XML file and dynamically create a table displaying the data. Where I am getting stuck at is when I am trying to get the totals from a specific column and then displaying them at the bottom. For example;
Column 3 3 5 6 Total 14
I can actually create and console.log a listNode but I can't necessarily do anything with that list. Thanks for your help.
This is the HTML code:...

You're using query selector already, but not to its full potential. You can use it to fetch the child elements by name, which makes your code a lot more readable and maintainable.
If you use
Àrray.from() to convert the records into an array, you get access to the
reduce() method. This allows you to reduce the list of XML elements into specific totals.
I am coding a table with values. The values come from an xml doc.
What I need help with is in one of the columns I am trying to assign a value to a td and every time the loop goes around it adds the current value to the previous value.
Sort of like a number incremented by its own value.

Use an accumulator variable that you add to each time through the loop.
"R3+2-1R2+1-1R2+0-2" is my input, I'm trying to figure out the total number of positive tests (value after + sign) in the string input. I think the function might be entering an infinite loop, but I'm not sure why......

Here I've revamped the inner loops a bit to make sure
j gets incremented correctly.
I'm trying to build a heuristic for the simplest feasible Golomb Ruler as possible. From 0 to n, find n numbers such that all the differences between them are different. This heuristic consists of incrementing the ruler by 1 every time. If a difference already exists on a list, jump to the next integer. So the ruler starts with [0,1] and the list of differences = [ 1 ]. Then we try to add 2 to the ruler [0,1,2], but it's not feasible, since the difference (2-1 = 1) already exists in the list of differences. Then we try to add 3 to the ruler [0,1,3] and it is feasible, and thus the list of differences becomes [1,2,3] and so on. Here's what I've come to so far:...

For efficiency I would tend to use a set to store the differences, because they are good for inclusion testing, and you don't care about the ordering (possibly until you actually print them out, at which point you can use
You can use a temporary set to store the differences between the number that you are testing and the numbers you currently have, and then either add it to the existing set, or else discard it if you find any matches. (Note
else block on
for loop, that will execute if
break was not encountered.)

You can use POStest like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the POStest component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
