Solution: Divide Array Into Increasing Sequences

Explore how to determine if a sorted integer array can be divided into one or more increasing subsequences of at least length k. Understand tracking the frequency of consecutive elements and using this to verify the partition's feasibility, optimizing space and time complexity efficiently.

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.
