Answers
A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.
Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.
Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.
Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.
The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.
The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.
Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.

The solution for the variable "m" in the equation 2 - m = 7 is -5.

2 - m + m = 7 + m
Simplifying the left side of the equation:
2 = 7 + m
Then, subtracting 7 from both sides of the equation
2 - 7 = 7 + m - 7
Simplifying the left side of the equation:

You have been asked to write a loop that outputs values in a database column ranging between 10 and 100. Any number that is not divisible by 5, and any value that is not an integer, should be ignored. When the value in the loop hits 95, break the loop prematurely. One of your team members has advised the use of break, continue, and pass statements.
Answers
Explanation:
This is going to depend on the language you're working in heavily.
First you will want to verify your number is an integer rather than a floating point which will completely depend on the language and whether you care if the floating point is 1.0 for example, which could still be converted a valid integer value.
After you've determined if it is an integer you can use modulo to check if the integer is evenly divisible by 5. In C-like languages you would write this as `x % 5`. Any result other than zero would mean it is not evenly divisible.
You also need to check if the integer is >= 10 and <= 100.
Read up on for/while loops and break/continue in those loops to understand that concept, it is pretty universal to all languages.
