Classes are just syntactic sugar meant to encapsulate code and abstract(hiding unnecessary details) code. The code would still work in this case without classes and by simply just writing the function

Study math

Yes Of Course it can simply work without classes. Just write the function outside of the class code block literal and invoke the function like this: findSmallestInt([23, 45, 67])

Very hard for beginner!

Not intuitive for me but glad to know it exists.

Helpful. Thank you!

Someone told me to go back to school to study math; it will help my programming. I see the point.

So you can tell the program when you want to exit the function and get the value you're looking for.

Beginner here. Could someone explain why the return key word is being used here? Thanks.

Good to know there is a built-in fcn for checking for integers.

I would rename p as "total" and n as "current" or something like that for readability.
