Your question is Debug a Technical Issue. Start with the requirements on the right.

Problem

Describe a scenario where you solved a technical issue by debugging code. As a coding follow-up, inspect the duplicate-detection behavior and implement the corrected function. Given a list of values, return the indices of the first value whose second occurrence is encountered, or [-1, -1] when every value is unique. For example, [4, 1, 4] returns [0, 2], while [2, 3] returns [-1, -1].

Constraints

0 <= values.length <= 1000
Values may be positive, zero, or negative integers
Return the pair for the earliest second occurrence
Return [-1, -1] when all values are unique
