Consider a Blazor Server application that implements a simple component for displaying user profiles. The component is designed to fetch user data asynchronously from an API upon initialization and update its state accordingly. The component also includes a button that, when clicked, updates a piece of local state within the component. Consider the following pseudo-code representation of the component:

Assuming the component is navigated to and then navigated away from, which of the following correctly lists the order in which lifecycle methods and event handlers are called, including `Dispose` for cleanup?

A: OnInitializedAsync, FetchUserDataAsync, UpdateUserStatus, Dispose
B: FetchUserDataAsync, OnInitializedAsync, UpdateUserStatus, Dispose
C: OnInitializedAsync, FetchUserDataAsync, Dispose, UpdateUserStatus
D: FetchUserDataAsync, UpdateUserStatus, OnInitializedAsync, Dispose
E: OnInitializedAsync, Dispose, FetchUserDataAsync, UpdateUserStatus
F: Dispose, FetchUserDataAsync, OnInitializedAsync, UpdateUserStatus

Review the following JavaScript code and pick the correct options: 

Assume that the API returns a successful 200 response code and a JSON object as the response body. What would the value of ‘a’ be after the code is executed?

What will the output of the following JavaScript code be?

What does the following code output? 

What does the following JS code output?

We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount.

For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition.

⚠️⚠️⚠️ Note:
- The first line of the input is the length of the array. The second line contains all the elements of the array.
- The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function.
- You need to "print" the final result (not return it) to pass the test cases.

For the example discussed above, the input will be:
5
20 70 -40 30 -10

Your code needs to print the following to the standard output:
20 70 30 -40 -10

A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. 

Example:

Input:
WWMMWWCCC

Expected Output: 
4W3C2M

Explanation: 
‘W’ has the highest count, then ‘C’, then ‘M’. 

⚠️⚠️⚠️ Note:
- The input is already parsed and passed to a function.
- You need to "print" the final result (not return it) to pass the test cases.
- If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’.
- If any of them have the same count, the output should follow this order - M, W, C.
