Need a developer to work on ongoing react-native and java backend

Need a developer to work on the ongoing react-native app and java backend.

Majority of the work will be in the backend,

The backend is in Java (GRPC), MongoDB. As a developer, you'll need to implement, chat functionality in the app.

Previous experience with real-time messaging required.

Freelancer is required to solve a simple take-home test.

Given input numbers, (a, b) & (c,d) you can get two subsequent numbers from adding the former numbers with one another, i.e (a+b, b) or (a, a+b). And for each result, you can get a subsequent number in a similar fashion. You need to return boolean true or false, if (c,d) is present in such iteration or not.


input: (a=1, b=3) . (c=2,d=4)

output: false, there is no way to reach (2, 4) from adding a, b recursively in any way as stated above.

input: (a=1, b=3) (c=2, d =5)

output: true, since is possible to reach (1, 5) from adding a, b recursively in the way stated above.

Please provide solution coded in either javascript or java & upload it to your GitHub repo for review & provide accompanying readme stating how to run your program, please provide the link in your response. Thank you, happy to meet you :)
