Understanding the Apply Operations to Make All Array Elements Equal to Zero Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a 0-indexed integer array nums and a positive integer k. You can apply the following operation on the array any number of times: Choose any subarray of size k from the array and decrease all its elements by 1. Return true if you can make all the array elements equal to 0, or false otherwise. A subarray is a contiguous non-empty part of an array.

Examples
nums = [2,2,3,1,1,0], k = 3trueWe can do the following operations: - Choose the subarray [2,2,3]. The resulting array will be nums = [1,1,2,1,1,0]. - Choose the subarray [2,1,1]. The resulting array will be nums = [1,1,1,0,0,0]. - Choose the subarray [1,1,1]. The resulting array will be nums = [0,0,0,0,0,0].
nums = [1,3,1,1], k = 2falseIt is not possible to make all the array elements equal to 0.
Constraints
