            convert length to point in svg (polygon) dynamically
            Asked 2022-Feb-09 at 10:15

            I am doing a small assignment to find out the type of the triangle whether is equilateral, isosceles, or scalene based on the values a,b,c.

            my problem is that I couldn't manage to convert the a,b,c values in order to draw the shape by using SVG (polygon) since it takes points and I have only values



            Answered 2022-Feb-08 at 09:29

            This question probably belongs in Maths StackExchange, but anyway.

            Firstly, you need to first check whether it is possible for the combination of side lengths to form a triangle.

            The way to do that is with the Triangle Inequality Theorem. It states that each of the side lengths must be less than the sum of the other two.

            So in your example, the lengths [5,200,300] cannot form a triangle because 300 is not less than (5 + 200).

            Also, none of the lengths should be <= 0.

            So let's work with three valid side lengths: [150, 200, 300].

            The way to get the three points is to start with one side, and draw that first. So we will start with the side that is 150.

            You can draw that side anywhere, but let's make the line go from (0,0) to (150,0).

            To get the third point we need to find where the other two sides would meet. Imagine two circles centred at each end of that first line. Each circle has a radius corresponding to the remaining two side lengths. The way to calculate the third point is to find the instersection point(s) of those two circles.

            I would like to use some code line speed indicator related libraries such as scalene and tamppa to evaluate which code lines consume more times. We will need to run some command lines in the terminal, before and after the code execution, for seeing the results. For example using tamppa library, if we have the following code ( and execute it in PyCharm:

            Condition Returns True even if it isn't
            Asked 2022-Jan-23 at 11:50

            So i was writing a C program to check if a triangle is scalene, isosceles,or equilateral. But whenever i equate the three sides NOT to be equal, it still returns 1 (see condition on line 16).



            Answered 2022-Jan-23 at 11:50

            You are printing the same expression that you use in the if condition, so if the if expression is true, it will obviously print 1..



            How can I separate these inputs and still make them a float?
            Asked 2021-Nov-18 at 01:47

            A triangle can be classified based on the lengths of its sides as equilateral, isosceles or scalene. All 3 sides of an equilateral triangle have the same length. An isosceles triangle has two sides that are the same length, and a third side that is a different length. If all of the sides have different lengths then the triangle is scalene. Write a program that reads the lengths of 3 sides of a triangle from the user. Display a message indicating the type of the triangle

            And here is my code, which doesn't work:



            Answered 2021-Nov-18 at 01:47

            The reason your code doesn't work is because split() is a string function. You can't use it to an integer or float. So, it needs to be like this

            Pitest mutates Java source code in ways that seem not possible
            Asked 2021-Nov-05 at 12:21

            I wrote a simple program that given three integers representing the lengths of the sides of a triangle, outputs which type of triangle it is. Then I wrote a set of test cases and ran mutation coverage using pitest.

            My goal is to obtain a 100% mutation coverage which I think is doable since it is a very simple program.

            My problem is that pitest introduces mutations that I don't understand and thus don't know how to kill.

            Here is the program:



            Answered 2021-Nov-05 at 08:21

            Pitest mutates bytecode rather than source code. The mutators attempt to describe the equivalent change in the source file, but sometimes this is less than straightforward.

            These mutations look to have been generated by the 'rv' mutators. These are generally of lower quality than the standard set and are not reccomended for general use. Do not use them unless you have a particular reason to do so.

            The "incremented a local variable" should really read "incremented a the local variable or paramter". The operator would need to do additional analysis to work out which.

            The not equal to greater than mutation will have mutated a IFNE instruction in the bytecode. In the simplest case this will map to a != check as the mutation description suggests, but the compiler may choose to use this instruction when generated other logic constructs (in this case equality checks combined with an &&). The description is certainly misleading, updating the mutator to make it more accurate would however involve writing the large part of a decompiler.



            Get input for unknown class fields during runtime
            Asked 2021-May-16 at 13:16

            I've been learning C# the past couple of months and we've been tasked with a small project where there's this specific requirement:

            We need to design the UI part of the project in such way, that we can figure out some random class fields and then get the input from a user to initialize those fields.

            For example, in one run of the program we have this class A that has two integer fields. In the UI section, we need to figure out class A has two integers, then we need to receive 2 integers from the user and pass them back for initialization.

            Another scenario:

            We have class B that has a boolean and an Enum field, and we need to do the same.

            I've been leaning towards using reflection to gather the data needed in runtime, but I'm having a lot of problem figuring out how to actually receive the required input from user. Another hurdle is that we were told that reflection isn't gonna help us and/or not required to fulfill this task.

            I'm fairly inexperienced with the language so I assume there may be some other ways to implement this that I'm not aware of, but conceptually speaking - I really can't grasp how it is possible.

            Here's some basic classes hierarchy to give a better example:



            Answered 2021-May-16 at 13:16

            You could add a method to the base class that returns information on the fields that need to be initialized. Each shape then overrides this method and returns its respective fields.

            A second method is needed to actually initialize the fields after the UI got to know the required fields and had the user enter the values.

            The main problem then is that a subclass does not know about any private fields in its base class and can not initialize them. This can be solved by always calling the base implementation of GetFieldInfo() and InitFields() in every override.

            To ensure the collection of provided values is "consumed" correctly you could use a stack. Every base class will Pop() as many values from the collection it needs to initialize itself and then leaves the rest to its derived classes.

            The same principle is used when accumulating all the fields from base classes and derived classes with GetFieldInfo().

            Of course all this only works if the UI creates the Stack of values correctly, i.e. it must respect the order and Types it got via GetFieldInfo().

            Scalene has a new web-based GUI (demo here). Once Scalene has profiled your program, it will launch a web browser with an interactive user interface (all processing is done locally). Hover over bars to see breakdowns of CPU and memory consumption, and click on underlined column headers to sort the columns.
            Scalene is distributed as a pip package and works on Mac OS X, Linux (including Ubuntu in Windows WSL2) and (with limitations) Windows platforms. (Note: the Windows version isn't yet complete; it requires Python 3.8 or later and currently only supports CPU profiling.).


            A: Yes! There are several options:. A: In PyCharm, you can run Scalene at the command line by opening the terminal at the bottom of the IDE and running a Scalene command (e.g., python -m scalene <your program>). Use the options --html and --outfile <your output.html> to generate an HTML file that you can then view in the IDE. A: Pass in the --noreload option (see A: Scalene works with PyTorch version 1.5.1 on Mac OS X. There's a bug in newer versions of PyTorch ( that interferes with Scalene (discussion here:, but only on Macs.
