A simple android app built on Android Studio IDE using Java which calculates the factorial of a number.
- Enter any number less than 49000 in the number text field.
- The result will be displayed just below the space where you entered your input.
- Before exiting the app, it asks for your confirmation. Click "Yes" to exit your app or "No" to stay in the app.
For larger inputs, the app takes some time to compute the factorial of the number. So wait for a while until the result is displayed.
