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].

It is not true that the bullet will appear centered vertically in the cell when inserting bullet into a table cell.
A bullet, sometimes known as a bullet point, is an asterisk, black dot, circle, or other mark that appears before the text. When order is irrelevant, bullet lists are used to identify essential elements or to denote significance. In documents and presentations, bullet points are frequently used to assist organize information and make it simpler to read or understand.
A table cell is a subset of a chart table that is used to store information or data. Cells are arranged horizontally (in rows) and vertically (columns of cells). Each cell holds information about the combination of row and column heads with which it is collinear.
Whenever a bullet point is inserted in a table cell, by default the arrangement is in horizontal position (rows) at the left side of the designated cell, not in colums (vertically).

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.

At each step of its operation, the input to a Central Processing Unit is O A a program O B. an instruction O C. main memory OD.control unit
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 addressing information is recorded by a switch to build its MAC address table?
A.
The destination Layer 3 address of incoming packets
B.
The destination Layer 2 address of outgoing frames
C.
The source Layer 3 address of outgoing packets
D.
The source Layer 2 address of incoming frames
the source Layer 2 address of incoming frames is recorded by a switch to build its MAC address table.
What is MAC address?The switch's MAC address table maintains information about the other Ethernet ports to which it is linked on a network. Instead of broadcasting the data over all ports, the table allows the switch to deliver outgoing data (Ethernet frames) on the exact port necessary to reach its destination (flooding). Enter the show mac-address command to view the MAC table. The Type column in the output of the show mac-address command specifies whether the MAC entry is static or dynamic. The static-mac-address command is used to establish a static entry.
