Assignment7A: A new field of computer science: Small Data. Big Data is a really hot area in computing right now and there are tons of jobs in it. Here in FYE, we care more about the field of Small Data, because if you can work with small data, you can extend that to working with big data. For this assignment, you’re going to implement the most common operations on arrays. Specifically, initializing them, printing them, finding the min, finding the max, and finding the sum. These are used all the time, so our recommendation is to understand how to solve the underlying problem and use that as a model for solving harder problems. Write a program that creates an array of 100 integers. I would recommend “pre-initializing” each cell to either 0 or -1 before doing anything else because it will make things easier later. After that, you should write separate (static) functions for initializing the array (from user input - according to the behavior below), printing the array (according to the behavior below – only values that have been entered by the user), finding the minimum element of the array, finding the maximum element of the array, and finding the sum of all elements of the array. Assume that the values the user enters are between 0 – 99. Hint: a very convenient thing would be if your initialization function returned the number of elements the user typed in.

Enter a number or -1 to finish: 6

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Here are data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius. [Note: The numerical values in this problem have been modified for testing purposes.]
| Temperature (oC)(oC) | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Percent heat loss from beak | 34 | 35 | 33 | 33 | 35 | 48 | 54 | 52 | 45 | 50 | 44 | 54 | 59 | 62 | 64 | 64 |
The equation of the least-squares regression line for predicting beak heat loss, as a percent of total body heat loss from all sources, from temperature is: (Use decimal notation. Enter the values of the intercept and slope rounded to two decimal places. Use the letter ?x to represent the value of the temperature.)

• What does it mean for two variables, such as current and potential, to have a linear relationship to each other? Describe two devices— incandescent lamps and diodes— in which current and potential do not follow Ohm’s Law. Why are these two devices exceptions? Use Kirchhoff’s loop rule for potentials and junction rule for currents to describe how a single battery in a car can be used to power multiple electrical devices.

Write a program which takes three lists of names, and print out all the names only once. The expected runtime should be O(n) where n is the total number of names in the lists. You don’t have to sort the list. Use appropriate data structure to store the names, so add all data to the collection only once efficiently. The read-in list method and list1, list2, list3 is given. You may assume that the expected runtime of searching or inserting into a hash table is O(1). Do not call the list's contains method, because it slows down the run time.

Simple, short explanations, please.
A)Why might it be important to add a separator bar to a submenu item in the menu form? When a program has a lot of items for the user to select from, why should you avoid displaying all of the items on one menu?
B) Discuss the importance of GUI guidelines for menus. give an example of messy menus vs. well-organized menus, and how that affects the user experience.
C) Describe the three steps that must be taken when a data file is used by a program, why should a program close a file when it's finished using it?
D) Today, most information kept by companies is stored in databases. When might it be appropriate to use text files? (small amount of data, data needs randomly accessed?)

My code of sum function is wrong, I have no idea how to pass the data to sum function from readData function.
readData function can read the data from the file, it works.
Maybe the problem is still in the readData function, because I guess I did not store the data to memory(I am not sure)

In the RSA cryptosystem, it is possible that M = C, that is, the plaintext and the ciphertext may be identical.
Is this a security concern in practice?

| 1. | Sweet Corp. issued $19,100,000 par value 9% convertible bonds at 97. If the bonds had not been convertible, the company’s investment banker estimates they would have been sold at 95. | |
|---|---|---|
| 2. | Pharoah Company issued $19,100,000 par value 9% bonds at 96. One detachable stock purchase warrant was issued with each $100 par value bond. At the time of issuance, the warrants were selling for $4. | |
| 3. |
Suppose Sepracor, Inc. called its convertible debt in 2017. Assume the following related to the transaction. The 10%, $10,900,000 par value bonds were converted into 1,090,000 shares of $1 par value common stock on July 1, 2017. On July 1, there was $57,000 of unamortized discount applicable to the bonds, and the company paid an additional $81,000 to the bondholders to induce conversion of all the bonds. The company records the conversion using the book value method. |
