What should I prefer for my future in programming, web app or Android app development or competitive programming?

[chirag-garg]

Do what you love. If you love to solve problems go for competitive programming. If you love to develop things like web apps or Mobile Apps then go for Web/Android App development.

If you don’t have taste for any of these right now, go and find it.

Attend hackathons/programming contests, try all other technologies related to web(html/css/Node.js/ReactJS) and Mobile App(Android/iOS) and find your interest.
