Code to be written in Python
Will award brainliest automatically if correct!

Suppose that you have a list of numbers, and you need to normalize the list, i.e., the sum of all numbers in the list is equal to 1.

Tam came out with an implementation:

def normalize(lst):
s = sum(lst)
return list(map(lambda v: v / s, lst))


This code works correctly for normalize([1, 2, 5, 4]) but fails for normalize([1, 2, -7, 4]). What causes the second test case to fail?

Find out the error message and keep the list as it is when the error occurs by simply return the list. So without modifying the normalize function, implement this strategy in the safe_normalize function. Complete safe_normalize. You may assume that the normalize function has already been defined for you.

def safe_normalize(lst):
# handle the error
return normalize(lst)

Test Cases:

safe_normalize([1, 2, 2, 3]) [0.125, 0.25, 0.25, 0.375]
safe_normalize([1, 2, -5, 2]) [1, 2, -5, 2]

The correct answer is B) send an email to all employees and attach the insurance documents. This is the most efficient and effective way for Steve to disseminate the insurance documents to all employees. It allows employees to access the documents electronically, at their convenience, and ensures that everyone receives the same information. Option A) using a digital ink pen to scan handwritten notes is not a viable option for distributing the insurance documents to all employees. Option C) calling each employee and asking them to pick up the documents at Steve's desk is also not practical, as it would be time-consuming and may not be convenient for all employees. Option D) creating a presentation is not relevant to the task at hand.

Homes and Businesses use networks because it can help you better to find customers and staff and suppliers and business partners. Homes and Businesses also use network when it comes to conferences and you can also communicate through apps using the network.

There are many ways that homes and businesses use networks. Here are a few examples:

1. Home networks: Many homes have a local area network (LAN) that connects all of the devices in the home, such as computers, printers, and smartphones. This allows people to share resources, such as files, printers, and internet access.
2. Business networks: Businesses often have a more complex network setup, with a LAN that connects all of the devices in the office, as well as a wider area network (WAN) that connects multiple offices in different locations. This allows employees to share resources and communicate with each other, no matter where they are located.
3. The Internet: Both homes and businesses use the internet to connect to the rest of the world. This allows them to access a wide range of information and services, as well as communicate with people all over the globe.
4. Cloud computing: Many businesses and even some homes are using cloud computing, which allows them to store and access data and applications over the internet, rather than on a local server or computer. This can be more convenient and cost-effective, as it reduces the need for expensive hardware and IT staff.
5. Internet of Things (IoT): Both homes and businesses are using networks to connect a variety of devices that make up the Internet of Things (IoT). This includes things like smart thermostats, security cameras, and appliances that can be controlled and monitored over the internet.

Here is a Java program that includes a menu with the four functions you specified: Insert, Remove, Search, and Increase. The program uses an array named "List" to store the integral values, and allows the user to perform the specified actions on the array. I have also included a function called "Update" that allows the user to edit an existing value in the array based on their selection.

import java.util.Scanner;

public class ArrayMenu {
static Scanner input = new Scanner(System.in);
static int[] List = new int[10];
static int size = 0;

public static void main(String[] args) {
boolean exit = false;
while (!exit) {
System.out.println("Menu:");
System.out.println("1. Insert a value");
System.out.println("2. Remove a value");
System.out.println("3. Search for a value");
System.out.println("4. Increase the value of all elements by a percentage");
System.out.println("5. Update an existing value");
System.out.println("6. Exit");
System.out.print("Enter your choice: ");
int choice = input.nextInt();
switch (choice) {
case 1:
insert();
break;
case 2:
remove();
break;
case 3:
search();
break;
case 4:
increase();
break;
case 5:
update();
break;
case 6:
exit = true;
break;
default:
System.out.println("Invalid choice. Please try again.");
break;
}
}
}

public static void insert() {
if (size < 10) {
System.out.print("Enter a value to insert: ");
int value = input.nextInt();
List[size] = value;
size++;
} else {
System.out.println("Array is full. Cannot insert a new value.");
}
}

public static void remove() {
if (size > 0) {
System.out.print("Enter the index of the value to remove: ");
int index = input.nextInt();
if (index >= 0 && index < size) {
for (int i = index; i < size - 1; i++) {
List[i] = List[i + 1];
}
size--;
} else {
System.out.println("Invalid index. Please try again.");
}
} else {
System.out.println("Array is empty. Cannot remove a value.");
}
}

public static void search() {
System.out.print("Enter a value to search for: ");
int value = input.nextInt();
boolean found = false;
for (int i = 0; i < size; i++) {
if (List[i] == value) {
System.out.println("Value found at index " + i);
found = true;
}
}
if (!found) {
System.out.println("Value not found in the array.");
}

The earliest GUI-equipped PCs were Linux and Mac-based. These are the right answers to the question that was asked.

Which PCs had a graphical user interface (GUI) first?

The first computer to employ a mouse, the desktop metaphor, and a graphical user interface (GUI), concepts Douglas Engelbart first introduced while at International, was the Xerox Alto, developed at Xerox PARC in 1973. It was the first instance of what is now known as a full-fledged personal computer.

When was the GUI added to Windows?

Windows is based on what is known as a graphical user interface (GUI), which was created by Xerox in 1975 but was never used. The "window, icon, menu, and pointing device" (WIMP) combination will make up the majority of a typical GUI.
