What is the expected return type of the function 'fun f(p: ???): ???' that returns 'p.take(2) + p[p.size - 1].drop(1)'?
Understand the Problem
The question is asking to determine the expected return type of a function based on given code that involves taking elements from a collection and performing operations on them.
Answer
String
The expected return type is a string.
Answer for screen readers
The expected return type is a string.
More Information
The function manipulates a sequence using the take and drop methods, which are typically associated with string or list manipulation in some programming languages. Given p.take(2) and p[p.size - 1].drop(1), it's likely operating on a string or sequence, thus returning a string.
Tips
A common mistake might be misunderstanding the methods used (e.g., take, drop) based on the language being used and assuming operations on numerical lists rather than strings.
