Understanding the Apply Operations to Make Sum of Array Greater Than or Equal to k Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a positive integer k. Initially, you have an array nums = [1]. You can perform any of the following operations on the array any number of times (possibly zero): Choose any element in the array and increase its value by 1. Duplicate any element in the array and add it to the end of the array. Return the minimum number of operations required to make the sum of elements of the final array greater than or equal to k.

How Interview Coder Helps
Get real-time assistance for Apply Operations to Make Sum of Array Greater Than or Equal to k problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
k = 115We can do the following operations on the array nums = [1]: Increase the element by 1 three times. The resulting array is nums = [4]. Duplicate the element two times. The resulting array is nums = [4,4,4]. The sum of the final array is 4 + 4 + 4 = 12 which is greater than or equal to k = 11. The total number of operations performed is 3 + 2 = 5.
k = 10The sum of the original array is already greater than or equal to 1, so no operations are needed.
