I'm quite skilled with Java, Python, C++, etc. but have never done mobile development. I have used React to develop a web application before, however.
For a job, as a take-home exercise they have asked me to develop a very simple mobile application which lets the user input two numbers x and y and then show a shape with the number of sides being equal to the sum of x and y (e.g. if x = 2 and y = 3 then show a pentagon).
How can I achieve this? I don't have any mobile development experience but I really want to achieve this task.
There is no specific language stated to use (however, their company uses React Native, Firebase, Node.js and JavaScript)
