math2 | A math lib optimized for sparse calculation | Math library

Expanding the columns into math1, science1, math2, science2, etc. would not be "normalizing." It's an example of repeating groups, which is usually considered a violation of First Normal Form.

You said each of the multiple rows per person corresponds to a different exam. How would you know which exam each row goes with? Why not add a column exam_no?

1. As you mention, if you inspect the element of the login page, you can see that the MatCard is using the class login-container which applies a margin auto to the left and right side of the element. That's what is causing it to be centered.

1. Most likely, per the stylesheet you referenced, the wrapping elements on the login page reference the CSS located here. It's called .login-body and just like in item 1 above, it is using a margin of auto to center horizontally.

2. The login-body and login-container classes are applied to the pages by either the Shared/Components or the Shared/Layouts. For example, the Login page you reference in your question appears to be using the LoginLayout.razor here. There you can see that both of these classes are being used.

There are several problems here. First of all, there is the naming issue I mentioned in the comments. Second is the fact that you're checking courses[i].previous[j] !== null, when that should not be necessary, but if it was, you probably need to check against undefined instead... and you can do both by checking != null (one equals sign.)

But the big problem is that you're not declaring your loop variables. i and j are not declared, and so are global. When you change i inside paintPrevious, you are also changing it inside paint. Changing for (i = 0; ...) to for (let i = 0; ...) and similarly for j fixes your problem.

I donot think Spark or Scala provides inbuilt support for interpreting Math expressions using variable names

But you can work around this using java library ScriptEngineManager

Why wont it render geometry correctly?

Your position arrays are three vertices of two compoenents each (x, y), but you're telling GL they have three components each:

1. Collecting List to Map<...> using Java Stream API

The provided JSON output structure is not compatible with Map> but with multiple dictionaries nested as values. As far as I see, there are 3 levels: subject, unit1 and unit2. The final non-dictionary value is a List of unit3.

Therefore, the desired output is Map>>> and chained Collectors.groupingBy should be suitable for it:

You need to initialize the METAFILEPICT structure.

Minimal example:

While I totally forgotten about this question of mine, I've found a way a couple of days ago while reading this directives and construct for OPM: https://www.openmp.org/wp-content/uploads/OpenMP-4.5-1115-CPP-web.pdf.

So:
