modulo operation was expensive isn't it? it can be done without using module operation at all..

I like your recursive approach. That's something I didn't think of.

you can see his solution... there you will see why

impressive!

People should get into the habit of writing some text in their code for newer people

well it's an O(n) solution and there is an obvious O(1) solution

that's why it does not deserve its insane 250 upvotes

The collect call doesn't need a turbofish because the collection type is inferred by the return type

Put

enum Input {
  Text(String),
  Number(i32),
  Decimal(f64),
  ...
}

into the description may be better

explain further since you aren't making any sense.

Awesome!
