Question: The developers at Amazon IAM are working on identifying vulnerabilities in their key generation process. The key is represented by an array of n integers, where the th integer is denoted by keyli]. The vulnerability factor of the array (key) is defined as the maximum length of a subarray that has a Greatest Common Divisor (GCD) greater than 1. You are allowed to make a maximum of maxchange modifications to the array, where each modification consists of changing any one element in the array to any other value. Given an integer array key and an integer maxChange, find the least possible vulnerability factor of the key after making at most maxChange changes. Note: The length of an empty subarray is considered to be zero. Example key = [2, 2, 4, 9, 6] maxChange = 1

clarified requirements, spoke out my thoughts then drew a design diagram Ask many question DB, which, why, is it good to use two different DB? also discuss the flow of the design. when user login in new device, how the flow will happened.

I call recruiter after the one day. she didn't pick-up. i tried after one week for feedback, but she didn't pick the call.
