For this question you will perform two levels of quicksort on an array containing these numbers:
59 41 61 73 43 57 50 13 96 88 42 77 27 95 32 89
In the first blank, enter the array contents after the top level partition.
In the second blank, enter the array contents after one more partition of the left-hand subarray resulting from the first partition.
In the third blank, enter the array contents after one more partition of the right-hand subarray resulting from the first partition.
Print the numbers with a single space between them.
Use the algorithm we covered in class, in which the first element of the subarray is the partition value.

- The assignment here is to write an app using a database named CIT321 with a collection named students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of class. The database contains 51 documents.
