Efficient Cost

Problem Overview

• Partition an integer array into contiguous subarrays of length at most a threshold, with each subarray’s cost equal to its maximum; minimize the total cost.
• Input: int[] arr and int threshold; Output: int minimum cost; array order must be preserved; constraints unspecified.
• Applies to cost optimization in batching or segmenting data under size limits.
• A Snowflake interviews coding interview problem and interview question.
