I'm basically wondering what the optimal method for returning to the top of src/main.rs::main() is?

mod main;
pub fn main() {
crate::main();

Or maybe there's a keyword built in?
I want to handle certain kinds of errors by 'restarting the program'.
I am currently learning JAVA. I barely have any coding experience. I wrote a program which asks a user for a sentence. It then swaps the words of the sentence (first with last, second with second to last, etc.). Program will then output the new sentence.
I know that this is not the most optimal...

I have implemented the kaprekar's constant algorithm in c#, and I want your feedback.
Here is how the algorithm works:
it takes a number of 4 digits (e.g: 5823)
we order that number in ascendent and descendent order, which gives as two numbers (e.g: 8532 and 2358).
we subtract number larger n...
