Solution: Divide Array Into Increasing Sequences

Explore how to determine if a sorted array can be divided into one or more increasing subsequences each with a minimum length k. This lesson guides you through tracking element frequencies and applying an efficient linear algorithm in C# to solve this pattern-based coding problem.

Statement

Given a sorted integer array, nums, in non-decreasing order and an integer, k, determine whether it is possible to partition the array into one or more disjoint increasing subsequences, each having a length of at least k. Return true if such a partition exists; otherwise, return false.

Constraints:

  • 11 \leq k \leq nums.length10 ...
