Understanding the Subarray With Elements Greater Than Varying Threshold Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an integer array nums and an integer threshold. Find any subarray of nums of length k such that every element in the subarray is greater than threshold / k. Return the size of any such subarray. If there is no such subarray, return -1. A subarray is a contiguous non-empty sequence of elements within an array.

How Interview Coder Helps
Get real-time assistance for Subarray With Elements Greater Than Varying Threshold problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
nums = [1,3,4,3,1], threshold = 6
3
The subarray [3,4,3] has a size of 3, and every element is greater than 6 / 3 = 2. Note that this is the only valid subarray.
nums = [6,5,6,5,8], threshold = 7
1
The subarray [8] has a size of 1, and 8 > 7 / 1 = 7. So 1 is returned. Note that the subarray [6,5] has a size of 2, and every element is greater than 7 / 2 = 3.5. Similarly, the subarrays [6,5,6], [6,5,6,5], [6,5,6,5,8] also satisfy the given conditions. Therefore, 2, 3, 4, or 5 may also be returned.
Constraints
1 <= nums.length <= 105
1 <= nums[i], threshold <= 109
