The programming language used in the question is Java programming lamguage.
in java, the sign ";" signifies the end of each line and lines that begins with // represent comments. Using this understanding of end of lines and comments, the formatted code goes thus

public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_ELEMENTS = 8;
// Number of elements
int[] userVals = new int[NUM_ELEMENTS];
// User numbers
int i = 0;
// Loop index
int sumVal = 0;
// For computing sum
// Prompt user to populate array
System.out.println("Enter " + NUM_ELEMENTS + " integer values...");
for (i = 0; i < NUM_ELEMENTS; ++i) {
System.out.print("Value: ");
userVals[i] = scnr.nextInt();

The data structure used for file directory is called

Answers
Data structures used for file directories typically have a hierarchical tree structure, referred to as a directory structure. The tree has a root directory, and every file in that system has a unique path.
The simplest method of implementing a directory is to use a linear list of file names with pointers to the data blocks. But another way that you can format a file directory is by using a hash table. With this method, the linear list stores the directory entries, but a hash data structure is also used. The hash table takes a value computed from the file name and return the pointer to the file name any linear list.

A Web server has five major components that must all function in order for it to operate as intended. Assuming that each component of the system has the same reliability and one of the components will have a backup with a reliability equal to that of any one of the other components, what is the minimum reliability each one must have in order for the overall system to have a reliability of 0.696
Answers
Answer:
The answer is below
Explanation:
Let x represent the reliability of each of the five major components. Since all the components must function before the system operates, hence they are in series with each other.
One component has a backup of the same reliability, the reliability of the back up system = 1 - (1 - x)² = 2x - x²
Therefore the reliability of the system is:
x * x * x * x * (2x - x²) = 0.696
2x⁵ - x⁶ = 0.696
x⁶ - 2x⁵ + 0.696 = 0
Solving the polynomial equation online using byjus.com gives:
x = 0.915038
x = 1.97695
x = -0.632585 - 0.429075 i
x = -0.632585 + 0.429075 i
x = 0.186590 - 0.789741 i
x = 0.186590 + 0.789741 i
Since the reliability is not a complex number and it is less than or equal to 1, hence:
x = 0.915038, x ≅ 0.915

Adapt the procedure developed in Example 6 to rotate the square counterclockwise by incre- ments of a /9 about the origin. Stop when the square is in its original location and then rotate it in the clockwise direction until the square is in its original location again. You may want to rescale the axis by using axis ([-2,2,-2,2]). Include the M-file. Do not include the figure. Hint: Since you are performing a computation several times, you will want to use two for loops: one loop for the counterclockwise rotation and another one for the clockwise rotation.

How did early computing device such as Charles Babbage's analytical engine and Ada Lovelace's contributions set the foundation for modern computing
Answers
Early computing devices, such as Charles Babbage's Analytical Engine and Ada Lovelace's contributions, played a crucial role in setting the foundation for modern computing. Here's how their work contributed to computing development:
1. Charles Babbage's Analytical Engine: Babbage designed the Analytical Engine, a mechanical general-purpose computer concept, in the 19th century. Although the Analytical Engine was never fully built, its design and principles laid the groundwork for modern computers. Key features of the analytical engine include:
a. Stored Program: Babbage's Analytical Engine introduced the concept of storing instructions and data in memory, allowing complex calculations and tasks.
b. Control Flow: The Analytical Engine could make decisions and perform conditional operations based on previous computations, resembling the modern concept of control flow in programming.
c. Loops: Babbage's design incorporated looping mechanisms, enabling repetitive instruction execution, similar to modern programming languages.
2. Ada Lovelace's Contributions: Ada Lovelace, an English mathematician, collaborated with Charles Babbage and made significant contributions to computing. Her work on Babbage's Analytical Engine included writing the first algorithm intended for machine implementation. Lovelace realized the potential of the analytical engine beyond numerical calculations and recognized its capability for processing symbols and creating complex algorithms. Her insights laid the foundation for computer programming and algorithms.
Lovelace's ideas about the analytical engine extended beyond what was initially envisioned. He stressed the importance of machines handling more than just numbers. Her contributions demonstrated computers' potential to perform tasks beyond basic calculations and numerical processing.
Collectively, Babbage's analytical engine and Lovelace's contributions provided early conceptual frameworks for modern computing. Their ideas influenced subsequent pioneers in the field, and the concepts they introduced paved the way for the development of the digital computers we use today.
