Practice Minimum Cost to Split an Array
Read the task, work through the examples, and check your approach against the constraints. Use the original LeetCode task for coding and submissions.
Problem Statement
You are given an integer array nums and an integer k. Split the array into some number of non-empty subarrays. The cost of a split is the sum of the importance value of each subarray in the split. Let trimmed(subarray) be the version of the subarray where all numbers which appear only once are removed. The importance value of a subarray is k + trimmed(subarray).length. Return the minimum possible cost of a split of nums. A subarray is a contiguous non-empty sequence of elements within an array.
