Answer 2

The function returns in the first iteration.

The return keyword will terminate the function execution. Therefore breaking the loop

Use yield instead of return

Answer 3

Gordon Generators will be a cleaner solution imo. Look at my code.

Answer 4

Your first return escapes the function, so the for loop stops at first iteration.

Declare a string variable in the functional scope,
Concantenate it in each iteration,
Return the string once only after the loop.
