reteach | Convert Blackboard 9 courses into Moodle 1.9 courses | Learning library

so ive done coding before but for some reason i cant seem to figure this one out and i keep over thinking the solution. so to summarize, the first method is supposed to return 1 oys, the second method should return 3 oys, and the third methods needs to return 5 oys. i've linked an screen shot to the project, it isn't for school or anything like that, just a friend trying to reteach me java, and then eventually full stacks sql. i mainly have dealt with android. project

So while working through a course on Udemy over C++ one of the challenges was to check a string to see whether it was a palindrome or not. I completed the task successfully but went about it a different way than the instructor. I understand there are a multitude of ways to complete a task but I am wondering which is more efficient and why? It may seem stupid to be wondering about this while reteaching myself coding but I feel this is something I should be keeping in mind.

I'm working on writing a simple program to move a stepper motor in C#. I have some past experience in C++, but have decided to transition over, as I'd have to reteach myself a bit of C++.

Previously, I've controlled the motor (using an Applied Motion ST5 Stepper Controller) with serial commands via PuTTY. My thought is that I could just send the same commands using C# by opening the correct COM Port (which works fine, as it crashes when I feed in a nonworking port number), and sending a string over. However, when I send a string of the same command that I had been using via serial terminal (FL1000, followed by a carriage return, it tells the motor to move 1000 steps clockwise), the motor does nothing. WriteLine should be the correct thing to use here, as it sends the string then a return, correct?

Does anybody see any glaring mistakes that would make my string not make it to the controller?
