This coding assessment comprises a series of programming challenges ranging from easy to hard. Each challenge is designed to evaluate your coding skills, problem-solving abilities, and, in some cases, your proficiency with specific tools or libraries.
Candidates are expected to complete the test independently. Any form of plagiarism, cheating, or seeking external help is strictly prohibited.
You are required to complete the questions within 1 week of the release.
You have the flexibility to choose your programming language for most questions. However, some questions specify the use of a particular language.
For the ROS (Robot Operating System) question, you need to have Ubuntu 20.04 and ROS Noetic installed on your system.
You will need to fork this repository and submit your solutions via pull requests.
The name of forked repo should be If a person name is Rahul Kumar , repo name will be rahulkumar_horizon
We strongly encourage you to provide clear and concise documentation alongside your code. This documentation should include comments, explanations, and instructions on how to run your programs or simulations.
Write a program that continuously accepts numbers as input and displays the average of all the inserted numbers. However, the program should not accept the same number more than once.
Input: 4 Output: 4
Input: 5 Output: 4.5
Input: 5 Output: 4.5
- You can use any programming language for this question.
- The program should keep reading numbers until the user decides to exit.
- If a number is repeated, it should not be included in the calculation of the average.
- Ensure that the code is well-documented and easy to understand.
The current position of a particle is (0,0) units. You will be provided with (velocity, direction, time interval) in unit/s, in degrees, and in seconds as an array. Write a C++ program to calculate the final position in (x, y) coordinates.
Input: ((5, 0, 2), (1, 45, 3), (2, -45, 1)) Output: (10.707, 0.707)
- Write a C++ program to calculate the final position based on the given inputs.
- Assume that the particle starts at (0,0) and moves according to the provided parameters.
- Make sure the code is well-structured and includes comments to explain the logic.
Install ROS Noetic on your system (Ubuntu 20.04) and implement a subscriber-publisher system in C++.
- You need to install ROS Noetic, which requires Ubuntu 20.04. Make sure you have the necessary system requirements before attempting this question.
- Implement a subscriber-publisher system in C++ using ROS. You can choose the topic and message type.
- Provide documentation for setting up ROS and running your code.
- The code should be well-commented and easy to understand.
- Include a brief explanation of what your subscriber-publisher system does.
Write C code in Tinkercad for Arduino to control a servo motor using a potentiometer. The servo should not go beyond 68 degrees and should turn on an LED if it exceeds 68 degrees. You need to submit a video of this circuit simulated in Tinkercad and the source code.
- Use Tinkercad to simulate the circuit.
- Provide a video demonstrating the simulation.
- Write C code for Arduino to control a servo motor using a potentiometer. The servo should not exceed 68 degrees, and if it does, it should turn on an LED.
- Share the source code along with any necessary instructions for setting up and running the simulation.
- Ensure that the source code is well-commented and easy to understand.
Good luck with your coding assessment! If you have any questions or need clarifications, please don't hesitate to ask.
