csc104 week 1

  In this week, basically what I learned is apply the function to the lists， first thing I learned is apply numbers, such as typing "apply + 1 2 3 (list 4)", what you will get is 1+2+3+4 which is 10. Another example, typing "(apply +（map string-length( list "I" "am" "writing" "assignment"))）, I will get 20. However, I did get a little confused about the previous stuff about recreating the image, and how to transforming the color to another one. I am going to watch the video again in order to clear understand this.
