Implement a simplified version of a crypto broker platform. Initially, there is an array of users, with each user depositing only cash - deposits[i] is the amount of cash the (i + 1)th user has deposited.
Assume that for now the platform contains just a single stock and all operations are done with this stock only. All operations are supposed to be in the same currency, and currency exchange is not supported for now.
The platform should support the following 3 types of operations:
"deposit " - deposits money to the specified user account.
"buy " - the specified user buys the specified amount of crypto at the specified price. The platform should make sure the user has enough money in their account to process the operation.
"sell " - the specified user sells the specified amount of crypto at specified price. The platform should make sure the user has enough cryptos in their account to process the operation.
Your task is to return an integer array representing the total amount of money in the specified user's account after each operation.
Example
For deposits = [9, 7, 12] and
operations = [
"buy 1 3 2",
"sell 1 4 10",
"deposit 2 12",
"buy 2 10 2",
"buy 2 6 3"
]
the output should be cryptoTrading(deposits, operations) = [3, 3, 19, 19, 1].
Let's consider all operations:
The user with user_id = 1 wants to buy 3 shares of the stock at price = 2 - the required amount of money is needed_money = 3 * 2 = 6. The user has 9 ≥ 6 units of money in their account, so this operation will be processed successfully. After this operation, the user has 3 units of money remaining.
The user with user_id = 1 wants to sell 4 shares of the stock at price = 10 - this operation will not be processed successfully because the user does not have 4 shares of the stock. Since the operation is not processed successfully, the user still has 3 units of money remaining.
The user with user_id = 2 deposits 12 units of money into their account. After this operation, the user has 19 units of money.
The user with user_id = 2 wants to buy 10 shares the stock at price = 2 - the required amount of money is needed_money = 10 * 2 = 20. The user has 19 < 20 units of money in their account, so this operation will not be processed successfully. The user still has 19 units of money remaining.
The user with user_id = 2 wants to buy 6 shares of the stock at price = 3 - the required amount of money is needed_money = 6 * 3 = 18. The user has 19 ≥ 18units of money, so this operation will be processed successfully. After this operation, the user has 1 unit of money remaining.
So, the output is [3, 3, 19, 19, 1].

when you are considering the layout of the product pages, it is important to put them in alphabetical order .
What is alphabetical order ?
We frequently arrange words and letters according to their alphabetical sequence. This signifies arranging them alphabetically. We consider the word's first letter when placing it in alphabetical order.
As an illustration, the letter c appears before the letter d in the alphabet, therefore the word "at" comes before "dog."
What does the alphabetical order for children mean?
When names, terms, or words are indexed, they are put in alphabetical order so that they follow the same pattern as the alphabet's letters (A-Z).
An alphabetical list of challenging terms and their definitions is called a glossary. A glossary aids in the reader's comprehension of a word's meaning.

What is RFID?The term "radio-frequency identification," or RFID, refers to a technology in which a reader reads digital data encoded in RFID tags or smart labels (described below) using radio waves. In that data from a tag or label are captured by a device and stored in a database, RFID is similar to barcoding. Contrary to systems that use barcode asset tracking software, RFID has a number of benefits.
The most notable difference is that while barcodes need to line up with an optical scanner to read, RFID tag data can be read without being in line of sight. If you're thinking about implementing an RFID solution, take the next step and get in touch with the RFID specialists at AB&R® (American Barcode and RFID).

At each step of its operation, the input to a Central Processing Unit is an instruction.
The part of a computer that obtains and executes instructions is called the central processing unit (CPU). A system's CPU can be thought of as its brain. It is made up of a control unit, a number of registers, and an arithmetic and logic unit (ALU). The term "processor" is frequently used to refer to the CPU. The ALU performs mathematical, logical, and related processes as directed by the software.
The control unit directs the movement of data within the CPU, the exchange of data and control signals across external interfaces, and all ALU operations (system bus). The CPU has high-speed internal memory storage units called registers.
Some registers can be accessed by the user, or by the programmer via the machine instruction set. Other registers are solely reserved for the CPU to be used for control.
All CPU parts are synchronized by an internal clock. Megahertz (MHz), or millions of clock pulses per second, is a unit of measurement for clock speed. The clock speed simply gauges how quickly the CPU executes an instruction.

write python code to create a function called reward highest that will take in a dictionary as an argument, identify the student who received the highest score, update that student's grade to 100, and then return the updated dictionary.
Below is an example of how you could write a function to achieve this by using the python programming.
Coding Part:
def reward_highest(student_grades):
# Find the student with the highest grade
highest_grade = 0
highest_student = ""
for student, grade in student_grades.items():
if grade > highest_grade:
highest_grade = grade
highest_student = student
# Update that student's grade to 100
student_grades[highest_student] = 100
# Return the updated dictionary
return student_grades
You can call this function by passing it a dictionary of student names and grades, like this:
student_grades = {
"Alice": 87,
"Bob": 72,
"Charlie": 92
}
updated_grades = reward_highest(student_grades)
print(updated_grades) # { "Alice": 87, "Bob": 72, "Charlie": 100 }

what is linux?Linux (/links/ (listen) LEE-nuuks or /links/ LIN-uuks) is a group of free and open-source operating systems based on the Linux kernel, which Linus Torvalds initially made available on September 17, 1991. The kernel and other system-supporting programs and libraries, many of which are made available by the GNU Project, are often included in Linux distributions, which are how Linux is typically packaged. Many Linux versions have the word "Linux" in their name, while the Free Software Foundation prefers to refer to their operating system as "GNU/Linux" to stress the significance of GNU software, which has generated some debate.
Popular Linux distributions include Fedora Linux, Debian, and Ubuntu, the latter of which is made up of numerous more distributions and customizations, such as Xubuntu and Lubuntu. Red Hat Enterprise Linux and SUSE Linux Enterprise are examples of commercial distributions.

Which of the following is not a common network topology: a. Ring b. Diamond c. Star d.Tree
Diamond is not a common network topology.
What is a basic network topology?
A Network Topology is the arrangement with which computer systems or network devices are connected to each other. Topologies may define both the physical and logical aspects of the network. Both logical and physical topologies could be the same or different in the same network.
What are the 4 common topologies?
The 4 Different Types of Computer Network Topologies
Bus Topology. Star Topology. Ring TopologyMesh Topology.What is the most common network topology?
Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape. All data must travel through the central node before it reaches its destination.
How many common network topologies are there?
The study of network topology recognizes eight basic topologies: point-to-point, bus, star, ring or circular, mesh, tree, hybrid, or daisy chain.
Thus, a diamond is the correct option.

Which of the following is the default return value of functions in C++?
Answer:
In C++, if a function does not specify a return type, the default return type is int. If a function does not return a value, the default return value is undefined.For example, the following function has a default return type of int:
// Default return type is int
void foo()
{
// Do something
}
If you want the function to return a value, you can specify the return type and use the return statement to specify the value to be returned. For example:
int add(int x, int y)
{
return x + y;
}
This function has a return type of int and returns the sum of its two arguments.It's generally a good practice to explicitly specify the return type of a function, even if it's int, to make it clear to the reader what the function is expected to return.
