The binary number 1010101 converted to decimal is__________. Enter the answer.O 85O 90O 72O 11
Answer:85
Explanation:
In Binary, we have 8 bits, all powers of 2, going up to 128.
When you only have 7 digits, you just add 0's to the left until it's 8. So in this case it would 01010101. Each 0 means the bit is "off," and each 1 means the bit is "on."
The 1st bit, from left to right, equals 128. The next is 64, then 32, then 16, then 8, then 4, then 2, then 1.
Since this specific number is alternating between bits, we know it is:
64 + 16 + 4 + 1 = 85
Since these are the bits that are turned on. Hope this helps!

Code written in C to determine how long it takes for a population to reach a particular size from gathering user input 'start', 'end', and the program outputting the number of years it will take (based on the pre-set birth and death rate) for the 'start' to reach the 'end' population number.
Say we have a population of n llamas. Each year, n / 3 new llamas are born, and n / 4 llamas pass away.
Complete the implementation of population.c, such that it calculates the number of years required for the population to grow from the start size to the end size.
Your program should first prompt the user for a starting population size.
If the user enters a number less than 9 (the minimum allowed population size), the user should be re-prompted to enter a starting population size until they enter a number that is greater than or equal to 9. (If we start with fewer than 9 llamas, the population of llamas will quickly become stagnant!)
Your program should then prompt the user for an ending population size.
If the user enters a number less than the starting population size, the user should be re-prompted to enter an ending population size until they enter a number that is greater than or equal to the starting population size. (After all, we want the population of llamas to grow!)
Your program should then calculate the (integer) number of years required for the population to reach at least the size of the end value.
Finally, your program should print the number of years required for the llama population to reach that end size, as by printing to the terminal Years: n, where n is the number of years.
Example Tests: $ ./population Start size: 1200 End size: 1300 Years: 1
Example Tests: $ ./population Start size: -5 Start size: 3 Start size: 9 End size: 5 End size: 18 Years: 8
C program enters a loop which simulates population growth over time. Each loop's iteration updates population based on birth and death rates and increments years. Loop continues until the population is greater than or equal to final population size.
How to write a program in C for implementing population to calculate the number of years it takes for the population to grow from its initial size to its final size?#include <stdio.h>
int main(void)
{
int start, end, population, years = 0;
printf("Enter a starting population size (minimum 9): ");
scanf("%d", &population);
while (population < 9) {
printf("Population size must be at least 9. Try again: ");
scanf("%d", &population);
}
printf("Enter an ending population size: ");
scanf("%d", &end);
while (end < population) {
printf("Ending population must be greater than or equal to starting population. Try again: ");
scanf("%d", &end);
}
while (population < end) {
population += population / 3 - population / 4;
years++;
}
printf("Years: %d\n", years);
return 0;
}
Program prints (output) number of years until population reached its final size.

Define a function in c named CoinFlip that returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls function CoinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0.
Hint: Use the modulo operator (%) to limit the random integers to 0 and 1.
Ex: If the random seed value is 2 and the input is:
3
the output is:
Tails
Heads
Tails
Note: For testing purposes, a pseudo-random number generator with a fixed seed value is used in the program. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used for each test case.
The program must define and call the following function:
void CoinFlip(char* decisionString)
The Coin Flip function accepts a character array pointer as an input, creates a random integer using the modulo operator, then, depending on the value, sets the first character of the array to either "H" or "T."
Is coin tossing a random sampling?A excellent physical example of random selection is flipping a coin or rolling a die. There is a 50/50 chance of receiving heads when you flip a coin. If you flip a coin once and receive heads, you have a 50/50 probability of getting heads the next time.

'0' is added to the string as follows: *(decisionString + 1)
Enter the number of coin flips here: int numFlips; printf ("Enter the number of coin flips: "); scanf("%d", &numFlips); getchar(); / eat the newline character from the input buffer for (int I = 0; I numFlips; i++) int main() srand(time(NULL)); / seed the random number generator with the current time int CoinFlip(decisionString); / use the CoinFlip method to determine the outcome. char decisionString[6]; / define a string with a size of 6 to carry either "Heads" or "Tails"

Answer:
ArrayList<Seat> mySeats = new ArrayList<>();
trainSeats.add(new Seat());
trainSeats.get(0).reserve("John", "Smith", 44);
Explanation:
ArrayList<Seat> mySeats = new ArrayList<>();
This declares a reference variable called mySeats for an ArrayList of Seat objects and initializes it as an empty list.
trainSeats.add(new Seat());
This adds a new element of type Seat to an ArrayList called trainSeats. The new Seat object is created using the default constructor.
trainSeats.get(0).reserve("John", "Smith", 44);
This uses method chaining to get the element at index 0 in ArrayList trainSeats and call the reserve method on it with arguments "John", "Smith", and 44. This makes a reservation for John Smith, who paid $44.

What do you mean by Python Programming?Python is a high-level, interpreted programming language that was first released in 1991. It is named after the Monty Python comedy group and was created by Guido van Rossum. Python is known for its readability, simplicity, and ease of use. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming.
Here's a solution in Python to the problem statement:
def print_arrow(body, head):
for i in range(1, body + 1):
print("1" * i)
for i in range(head, 0, -1):
print("1" * i)
body = int(input("Enter body size: "))
head = int(input("Enter head size: "))
print_arrow(body, head)
This code takes two integers as input, representing the size of the arrow body and arrowhead. The function print_arrow takes these two values as parameters and uses nested for loops to print the arrow. The first for loop prints the body of the arrow, while the second for loop prints the head of the arrow.

Option a is correct. If a hard link is created to a file and the original file is deleted, the original file will be deleted, but the contents of the file can still be accessed using the hard link.
Which commands creates a hard link link to a file?By default, the ln command creates hard links. Use the -s option to create soft (symbolic) links. The -f option forces the command to overwrite existing files.
What happens if create a hard link to a file?A hard link has the same inode number as the original file, so it points to the same disk space as the original file. The content of the hard link remains the same even if the original file is renamed. A hard link is basically a link to the actual content of the original file.
What happens when one of the hard links is removed?Even if the user removes one of the hard links, the data is still accessible through the other remaining links. When the user deletes all shortcuts and no process has the file open, the operating system frees up the space occupied by the file.

A programmer is developing a word game. The programmer wants to create an algorithm that will take a list of words and return a list containing the first letter of all words that are palindromes (words that read the same backward or forward). The returned list should be in alphabetical order. For example, if the list contains the words ["banana", "kayak", "mom", "apple", "level"], the returned list would contain ["k", "l", "m"] (because "kayak", "level", and "mom" are palindromes). The programmer knows that the following steps are necessary for the algorithm but is not sure in which order they should be executed. Executing which of the following sequences of steps will enable the algorithm to work as intended?
I. First shorten, then keep palindromes, then sort
II. First keep palindromes, then shorten, then sort
III. First sort, then keep palindromes, then shorten
Pilihan jawaban
a. I only
b. II only
c. I and III
d. II and III
Based on the above statement, pick (D) is the correct one. Prioritize palindromes, then shorten, and then sort III. Sorting was followed by shortening and retaining palindromes.

An application lists all the files and subdirectories in its web folder. This indicates which of the following weaknesses on the application?
a. Directory Listing
b. Cross Site Scripting
c. Session Hijacking
Directory Listing is the correct response. The web folder of an application contains a list of all the files and subdirectories. This reveals application flaws with Directory Listing.
a subfolder is a computerised organisational directory that is nested inside another directory. Sections of your main website can be divided using subdirectories, which are content subfolders. Each subfolder shares the top-level domain (TLD) of your website, and its URL structure always follows the root domain. Examples of subdirectories include all of the following: example.com/shop. The subdirectory appears in a URL after the root directory or domain name. Therefore, hubspot.com/pricing might be a subfolder URL. Alternatively, it may be something more challenging like pricing/sales.hubspot.com. Typically, a single subdirectory within this tree structure is referred to as a directory or subdirectory, respectively.

False. A single query that excludes the result of a subquery returns the same result as two queries joined by the except operator when the second query matches the excluded subquery in the current release of MySQL (8.0.21).
What is single query?A single query only contains one SELECT statement, whereas a compound query may contain two or more SELECT statements. By using a specific operator to join the two queries, compound queries can be created. In the examples that follow, two queries are joined together using the UNION operator.
The command most frequently used in Structured Query Language is the SELECT statement. Access to records from one or more database tables and views is made possible by using it. Additionally, it retrieves the data that has been chosen and meets our requirements.
We can also access a specific record from a specific table column by using this command. A result-set table is the one that contains the record that the SELECT statement returned.

Write a function select of this type: 'a list ('a -> bool) -> 'a list that takes a list and a function fas parameters. Your function should applyf to each element of the list and should return a new list containing only those elements of the original list for which f returned true. (The elements of the new list may be given in any order.) For example, evaluating select ([1,2,3,4,5,6,7,8,9,10), is Prime) should result in a list like [7,5, 3,2]. This is an example of a higher-order function, since it takes another function as a parameter. We will see much more about higher-order functions in Chapter 9
The function select takes a list and a function as input parameters, applies the function to each element of the list, and returns a new list containing only those elements for which the function returns true.
Below is the implementation of select function in python programming.
def select(lst, func):
return [x for x in lst if func(x)]
This function takes a list lst and a function func as parameters. It applies the func to each element of the lst using a list comprehension and returns a new list containing only those elements for which the func returns true.
To use the select function to find prime numbers from a list, we can define the is_prime function as follows:
def is_prime(n):
if n <= 1:
return False
for i in range(2, int(n**0.5) + 1):
if n % i == 0:
return False
return True
Then, we can call the select function with the list and the is_prime function as follows:
lst = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
result = select(lst, is_prime)
print(result)
This will output: [2, 3, 5, 7], which are the prime numbers in the list.
The output of the code is attached.
