week 6

This week I got my test back. It was generally not bad but I made some stupid mistakes on the test. I didn't know that I need to describe the function of (require picturing-programs) as well, so I left it blank.  I lost mark for this. Also, I was confused about how to calculate fibonacci5. Now I know them so hopefully I won't make the same mistake since this time.

 This week was really hard for me because I had my German and Economic test on thursday and friday. During the classes I learnt some new functions on Dr.Racket. I learnt how to group values in to lists and structs, and the function of map. For example, to reverse the list of values and to extract the first item from the list and the the rest of the list as well. I also learnt how to create a struct consist of different of parts. For example, I could create a struct with the album name, the singer, and the time that is was published. Finally, I learnt how to transform the list into a new list using the function of map. I could transform a list of numbers into another list of numbers by using "add5" to them.

The quiz was all about these functions we learnt this week so it was easy.
