answer questions

This lab is very interesting. It's hard at first as you have to understand each command's meaning,
but it gets fun when you get to know the basic logic behind it.
I enjoyed the process of solving problems using the combination of different commands.

This lab is different than lab 1 as it was directly coded in terminal and you could see the direct result after each code
It's kind of logical thinking or math thinking, you need to figure out a way to break down one big problem into small pieces and achive one by one.

I feel that the individual commands looks simple, but the combination of them can achieve many functions.

I was stuck on 5, 7, 10. I use AI to help me figure out 5 but I'm still not sure if there's any other way that could achieve the function, will check with my group.
for 7, I don't know why all the frequencies are the same... for 10, I cannot understand the literal meaning of that question.
I also met some challenges on 8 or 9 (cannot remember), but I tried many times using pluck, then figured it out ; )

I might disucss with my group about these next week as this week we didn't finish this lab before the meeting. And I'm still working on my drawing project.
