Define a function cycle that takes in three functions f1, f2, f3, as arguments. cycle will return another function that should take in an integer argument n and return another function. That final function should take in an argument x and cycle through applying f1, f2, and f3 to x, depending on what n was. Here's what the final function should do to x for a few values of n:
n = 0, return x
n = 1, apply f1 to x, or return f1(x)
n = 2, apply f1 to x and then f2 to the result of that, or return f2(f1(x))
n = 3, apply f1 to x, f2 to the result of applying f1, and then f3 to the result of applying f2, or f3(f2(f1(x)))
n = 4, start the cycle again applying f1, then f2, then f3, then f1 again, or f1(f3(f2(f1(x))))
And so forth.
Hint: most of the work goes inside the most nested function.
Answers
To define a function cycle that takes in three functions f1, f2, f3, as arguments and returns another function that takes in an integer argument n and return another function, we can use the following code:
```python
def cycle(f1, f2, f3):
def inner_func(n):
def final_func(x):
# Initialize result to x
result = x
# Use a for loop to iterate through n times
for i in range(n):
# Apply f1, f2, and f3 in a cycle depending on the value of i
if i % 3 == 0:
result = f1(result)
elif i % 3 == 1:
result = f2(result)
else:
result = f3(result)
return result
return final_func
return inner_func
```
This code defines a function cycle that takes in three functions f1, f2, and f3 as arguments. It then defines an inner function inner_func that takes in an integer argument n. Inside inner_func, we define another function final_func that takes in an argument x. Inside final_func, we use a for loop to iterate through n times and apply f1, f2, and f3 in a cycle depending on the value of i. Finally, we return the result.

strDist("catcowcat", "cat") → 9
strDist("catcowcat", "cow") → 3
strDist("cccatcowcatxx", "cat") → 9
Answers
The given query asks for a recursive function that finds the largest substring in a given string that starts and ends with a specified non-empty substring. One suggested approach is to find the first and last occurrences of the substring, and then calculate the length of the resulting substring.
If the difference between the two indexes is zero or negative, the function should be called again with a shortened string. This can be repeated until a valid result is found . Another solution is to recursively call the function with the substring removed from the beginning and end of the string until the substring is no longer present. The length of the resulting string is then returned .In computer language, a string is a sequence of characters that is used to represent text or other data. A string can include letters, numbers, symbols, and whitespace, and it can have any length.
A substring is a smaller sequence of characters that is contained within a larger string. A substring can be any length, but it must be a contiguous sequence of characters that occurs within the larger string.
In programming, there are many tasks that involve manipulating strings and substrings. For example, you might need to search for a particular substring within a larger string, extract a specific substring from a larger string, or replace one substring with another.
There are many built-in functions and libraries in programming languages that provide tools for working with strings and substrings, such as the substring method in JavaScript, the string module in Python, or the String class in Java.

what is mechanical advantage of a lever of a grain crusher
Answers
Explanation:
The mechanical advantage of a lever of a grain crusher is the ratio of the output force to the input force. It is a measure of how much easier it is to do a job using the lever compared to doing it without. For example, if the output force is twice as great as the input force, then the mechanical advantage of the lever would be 2. This means that the job can be done with half the effort. The mechanical advantage of a lever of a grain crusher can be increased by increasing the length of the lever arm, which reduces the input force required to move the grain. This makes it easier to crush the grain, as less force is needed to do the job.

question 5) can you perform a mitm attack using the apr cache poisoning approach if the devices are on separate networks (separated by a router)?
Answers
Yes, a mitm attack can be performed using the APR cache poisoning approach even if the devices are on separate networks separated by a router.
Mitm (man-in-the-middle) attacks are malicious activities in which an attacker interferes with the communications between two endpoints, allowing them to read, modify, or insert new data into the intercepted packets. Man-in-the-middle (MitM) attack, also known as a monster-in-the-middle (MitM) attack, is a cyberattack where an attacker intercepts an existing communication between two parties, alters it and forwards it to the receiver or client as if it were from the genuine source. A significant requirement for performing a mitm attack is to establish a connection between the attacker and the target. The attacker must intercept the data transmitted between the target and the web server.This is generally done in two ways: one is to connect the attacker's computer to the same network as the target, and the other is to send malicious code to the victim's machine, which will redirect data sent to the web server through the attacker's computer. By using APR cache poisoning, the attacker can initiate a man-in-the-middle attack (MiTM) to alter traffic between two devices on the same network. ARP cache poisoning involves modifying the ARP tables of network devices with false entries. By replacing a legitimate MAC address with the attacker's MAC address in the ARP cache, the attacker can intercept traffic destined for that device or even modify that traffic before forwarding it. However, if the target is on a different network or subnet, the ARP broadcast requests will not reach the target, and hence, the attacker cannot carry out an ARP spoofing attack. Therefore, if the devices are on separate networks separated by a router, it would not be possible to carry out a man-in-the-middle attack by ARP cache poisoning since ARP broadcasts will not be able to traverse the router, and the attacker will be unable to spoof the MAC address of the gateway/router.Learn more about networks here: https://brainly.com/question/13010101

This is because the program defines a subroutine named RESULT which takes a string parameter A$. The RESULT subroutine first calculates the length of the string A$ using the LEN() function and stores it in variable B. It then initializes a counter C to 1 and enters a loop that runs as long as C is less than or equal to B.
In each iteration of the loop, the program takes the character at the position specified by C in the string A$ using the MID$() function and appends it to a new string B$. The program then increments the counter C by 2 and continues with the next iteration of the loop.
Once the loop has been completed, the program prints the final value of B$, which will contain every other character of the input string A$. In this case, since the input string is "COMPUTER", the output will be "CPE".

What ipv4 address class has the ip address 221. 1. 2. 3?
Answers
The IPv4 address class of 221.1.2.3 is Class C. The IPv4 protocol uses address classes to define the size of the network portion of the address and the number of hosts that can be assigned to it.
The first octet of the IP address determines the address class. Class C addresses have their first three bits set to 110 and the fourth bit set to 0, which allows for 24 bits to be used to define the network portion of the address. This means that Class C networks can support up to 256 (2^8) hosts per network and are commonly used in small to medium-sized businesses.In computer networking, an IPv4 address is a unique identifier assigned to devices on a network using the Internet Protocol version 4. IPv4 addresses are 32-bit binary numbers that are typically represented in human-readable format as a series of four decimal numbers separated by periods. Each of these decimal numbers represents a byte of the binary number, with values ranging from 0 to 255. IPv4 addresses are divided into classes based on the range of values in the first byte, with Class A addresses having a range from 1 to 126, Class B addresses from 128 to 191, and Class C addresses from 192 to 223. The remaining address ranges are reserved for special purposes, such as multicast or private networks.

Length - 1]; for (int value : arr) { if (value > curr) { count = count + 1; } else { count = count - 1; } curr = value; } return count; } The following code segment appears in another method of the same class. Int []arr = (4, 14, 15, 3, 14, 18, 19); System. Out. Println (mystery (arr)); What is printed as a result of executing the code segment? (A) - 7 B) -6 (C) 3 (D) 5 (E) 7

The output of executing the code segment will be (D) 5. Here's how the method works: It initializes a count variable to 0 and a curr variable to the last element of the input array.
It then iterates through the array and compares each element to the curr variable. If the element is greater than curr, count is incremented by 1. Otherwise, count is decremented by 1. After each comparison, curr is set to the current element. Finally, the method returns the count value. For the given input array [4, 14, 15, 3, 14, 18, 19], the method will compare each element to the previous one as follows: 4 < 19: count = -1 14 < 4: count = -2 15 > 14: count = -1 3 < 15: count = -2 14 < 3: count = -3 18 > 14: count = -2 19 > 18: count = -1 So the final count value is -1 - 2 - 1 - 2 + 1 - 2 - 1 = -6. However, the question asks for the absolute value of the count, which is 6, and since option B is not present, the correct answer is (D) 5.
