Detect Repeating Digits | Dataford Interview Questions

Given an array of integers, identify if the array has any repeating digits within it. Return a bool.

Implement has_repeating_digits(nums), where nums is a list of integers. Treat each integer's absolute decimal representation as a digit sequence. Return True if any number contains a repeated digit or if multiple array elements have the same digit count; otherwise return False.

Constraints

0 <= nums.length <= 10^4
-10^9 <= nums[i] <= 10^9
Use base-10 decimal digits
Negative signs are ignored

Function Signature
