Min Length Subarray with Bounded Average Solution

Problem Statement

You are given an array of integers `values` and a target average `threshold`. Determine the minimum length of a contiguous subarray such that the average of the elements in this subarray is less than or equal to `threshold`. If no such subarray exists, return `-1`.

Constraints

• A is an array of integers.
• avg is a number.
• The length of A is between 1 and 10^6.
• The elements of A are between -10^6 and 10^6.
