Registration Queue
Logic
Queues
Sorting By Custom Order
Solve
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

Visitors Count
Strings
Logic
String Parsing
Character Counting
Solve
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.

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the JQuery Online Test?

Selectors: Selectors in jQuery are used to select and manipulate HTML elements. They allow you to target specific elements based on their IDs, classes, attributes, or other characteristics to perform actions on them. This skill is measured in the test to assess the candidate's ability to identify and manipulate specific elements using jQuery selectors.

Events: Events in jQuery are actions or occurrences that happen on a web page, such as a button click or a mouse hover. jQuery provides a convenient way to attach event handlers to these events, allowing developers to write code that responds to user interactions. This skill is measured in the test to evaluate the candidate's understanding of event handling and their ability to write code that responds to user actions.

DOM Manipulation: DOM manipulation in jQuery refers to the ability to dynamically modify the structure and content of a web page. This includes adding, removing, or modifying HTML elements, changing CSS properties, and updating the content of elements. This skill is measured in the test to assess the candidate's capability to manipulate the DOM using jQuery methods and functions.

Effects: Effects in jQuery are animations and transitions that can be applied to web elements. These effects can enhance the visual appeal and interactivity of a webpage. jQuery provides a wide range of built-in effects, such as fading, sliding, and toggling, to create smooth and engaging user experiences. This skill is measured in the test to evaluate the candidate's proficiency in applying effects to elements and creating visually appealing webpages.

Animations: Animations in jQuery involve creating custom animations by manipulating CSS properties over a period of time. This allows developers to bring elements to life with smooth and dynamic movement. jQuery provides intuitive methods and functions to animate elements, making it easier to create interactive and engaging web experiences. This skill is measured in the test to assess the candidate's ability to create and control animations using jQuery.

AJAX: AJAX (Asynchronous JavaScript and XML) is a technique that allows web pages to be updated asynchronously by exchanging data with a web server in the background. jQuery simplifies the process of making AJAX requests and handling the responses, making it a popular choice for implementing dynamic web applications. This skill is measured in the test to evaluate the candidate's understanding of AJAX and their ability to utilize jQuery's AJAX functionalities.

Forms: Forms in jQuery involve working with HTML forms, capturing user inputs, and performing validation and submission actions. jQuery provides powerful form manipulation functions and plugins that simplify the process of handling form elements and validation. This skill is measured in the test to assess the candidate's ability to work with forms and utilize jQuery's form-related functionalities.

Validation: Validation in jQuery refers to the process of checking and validating user inputs in forms to ensure that they meet certain criteria or constraints. jQuery offers various validation plugins and methods that can be used to validate form inputs, display error messages, and control the submission process. This skill is measured in the test to evaluate the candidate's knowledge of form validation techniques using jQuery.

Plugins: Plugins in jQuery are additional libraries or scripts that extend the functionality of jQuery. They can be used to add specific features or behaviors to web pages, such as sliders, carousels, or date pickers. This skill is measured in the test to assess the candidate's awareness and familiarity with popular jQuery plugins and their ability to incorporate and utilize them in web development projects.

Traversal: Traversal in jQuery refers to the ability to navigate and traverse the DOM tree to access and manipulate elements based on their relationships with other elements. jQuery provides a rich set of traversal methods and functions that allow developers to easily select and traverse elements in different directions, such as parent, child, sibling, or descendant elements. This skill is measured in the test to evaluate the candidate's understanding and proficiency in traversing the DOM using jQuery.

CSS Manipulation: CSS manipulation in jQuery involves dynamically changing or applying CSS styles to web elements. jQuery provides methods and functions to modify CSS properties, add or remove CSS classes, and perform other CSS-related operations. This skill is measured in the test to assess the candidate's ability to manipulate and control the appearance of elements using jQuery's CSS manipulation capabilities.

Attributes: Attributes in jQuery refer to the various HTML attributes associated with web elements, such as ID, class, src, href, etc. jQuery allows developers to read and modify these attributes using dedicated methods and functions. This skill is measured in the test to evaluate the candidate's understanding of working with attributes in jQuery and their ability to manipulate and utilize them effectively in web development projects.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.
