Briefly describe the issues involved in using ATM technology in Local Area Networks
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.
