HTML documents are plain text files that contain a series of HTML elements, each of which is represented by a tag. These tags are surrounded by angle brackets and provide information about the structure and content of a web page. For example, the <h1> tag is used for headings, the <p> tag is used for paragraphs, and the <a> tag is used for creating links.
HTML is an essential technology for web development, and it has evolved over the years to include new features and capabilities. The latest version of HTML, HTML5, includes new elements and attributes that make it easier to create rich, multimedia-rich websites, and it is supported by all major browsers.

4.15 LAB: Varied amount of input data
Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the max and average. A negative integer ends the input and is not included in the statistics. Assume the input contains at least one non-negative integer.
Output the average with two digits after the decimal point followed by a newline, which can be achieved as follows:
printf("%0.2lf\n", average);
Ex: When the input is:
15 20 0 3 -1
the output is:
20 9.50
In C programming language NOT C++
The program that takes any number of non-negative integers as input, and outputs the max and average is in explanation part.
What is programming?Making a set of instructions that instruct a computer how to carry out a task is the process of programming. Computer programming languages like JavaScript, Python, and C++ can all be used for programming.
Here is a Python program that takes any number of non-negative integers as input and outputs the max and average:
numbers = []
while True:
num = int(input())
if num < 0:
break
numbers.append(num)
max_num = max(numbers)
average = sum(numbers) / len(numbers)
print(max_num)
print("%.2f" % average)
Thus, the program uses a while loop to continuously read in input until a negative integer is entered, at which point the loop breaks.

You have been asked to temporarily fill in for an administrator who has just been fired. This administrator was known to have lax security standards, and you suspect that passwords are still kept in the /etc/passwd file.
Which of the following entry within the passwd file would indicate that the passwords are stored there?
In the /etc/passw-d file, the entry that indicates that passwords are stored there is the second field, which is usually marked as an "x" or "*".
This indicates that the passwords are stored in the shadow file, rather than in the /etc/passw-d file. The shadow file is a separate file that stores encrypted passwords, and is typically only accessible to the root user.
A password is a string of characters that is used to verify the identity of a user during the authentication process. Passwords are typically used to protect sensitive information, such as online banking or email accounts, or to control access to computer systems.

In Java
Write a multi-way if/else statement that
adds 1 to the variable minors if the variable age is less than 18,
adds 1 to the variable adults if age is 18 through 64 and
adds 1 to the variable seniors if age is 65 or older.
Here's an example of a multi-way if/else statement in Java to add 1 to the variable minors, adults, or seniors based on the value of the variable age:
int age = 30;
int minors = 0;
int adults = 0;
int seniors = 0;
if (age < 18) {
minors++;
} else if (age >= 18 && age <= 64) {
adults++;
} else {
seniors++;
}
In this example, the 'if' statement checks if 'age' is less than 18. If it is, then the value of 'minors' is incremented by 1. If not, the 'else if ' statement checks if 'age' is between 18 and 64, inclusive. If it is, then the value of 'adults' is incremented by 1. If neither of the previous conditions is met, the 'else' statement runs and increments the value of seniors by 1.

Write a function that receives a StaticArray and returns a new StaticArray with the same content sorted in non-ascending order. The original array must not be modified.You may assume that the input array will contain at least one element and that all elements will be integers in the range [-109, 109]. It is guaranteed that the difference between the maximum and minimum values in the input will be less than 1,000. You do not need to write checks for these conditions.Implement a FAST solution that can sort at least 5,000,000 elements in a reasonable amount of time (under a minute). Note that using a traditional sorting algorithm (even a fast sorting algorithm like merge sort, shell sort, etc.) will not pass the largest test case of5M elements.HINT: The name of the algorithm may seem confusing if not deceptive - it’s really not a sort as you might commonly view one. While the end result is a sorted version of the original contents, the means by which we arrive at it may be a bit different.For example, a sorted array can be generated if you know what values are present and how many times they occur. Note that you’ve already written code in this assignment that will help you determine how many different values could be in the array as well as the range of possible values present.RESTRICTIONS: You are NOT allowed to use ANY built-in Python data structures and/or their methods in any of your solutions. This includes built-in Python lists, dictionaries, or anything else. Variables to hold a single value or a tuple holding two/three values are allowed. It is OK to use built-in Python generator functions like range().You are NOT allowed to directly access any variables of the StaticArray class (like self._size or self._data). All work must be done by using the StaticArray class methods.

Describe Python Programming?It is known for its simple, easy-to-read syntax, which emphasizes readability and reduces the cost of program maintenance. Python is widely used in a variety of applications, including web development, scientific computing, data analysis, artificial intelligence, and more.
One of the key strengths of Python is its vast standard library, which provides a wide range of modules for tasks such as connecting to web servers, reading and writing files, and working with data. This makes it easier for programmers to get started with Python, as they can quickly leverage existing code to perform common tasks.
def sortArray(staticArray):
size = staticArray.size()
max_value = staticArray.max()
min_value = staticArray.min()
range_ = max_value - min_value + 1
count = [0] * range_
for i in range(size):
count[staticArray.get(i) - min_value] += 1
result = StaticArray(size)
idx = size - 1
for i in range(range_ - 1, -1, -1):
for j in range(count[i]):
result.set(idx, i + min_value)
idx -= 1
return result
This solution uses counting sort algorithm to sort the elements of the StaticArray in non-ascending order. The count list stores the frequency of each element in the original array. The loop from range range_ - 1 to 0 is used to iterate over the count list in reverse order so that the elements in the result array will be sorted in non-ascending order.

Hash functions are deterministic, meaning they will always produce the same hash value for a given input, and are designed to be fast to compute the hash value for any given input, but slow to generate the input from the hash value. Additionally, hash functions are designed to be collision-resistant, meaning it is difficult to find two different inputs that produce the same hash value.
What is a Hash Value?A hash value, also known as a message digest or digital fingerprint, is a unique, fixed-size string of characters generated from a larger piece of data, such as a file or a password.
Hash values are commonly used in cryptography to verify the integrity of data by comparing the original and calculated hash values, as well as in digital signatures and data structures (e.g., hash tables) to index and retrieve data quickly.
Common hash algorithms include SHA-1, SHA-256, and SHA-3, among others, with each algorithm having different strengths and weaknesses. It is important to use secure hash functions, as hash values can be vulnerable to attacks such as collision attacks, preimage attacks, and length-extension attacks.
