Solution: Divide Array Into Increasing Sequences
Explore how to determine if a sorted array can be partitioned into disjoint increasing subsequences each of at least length k. Understand how tracking the frequencies of consecutive elements helps decide if such partitioning is possible, and implement an efficient O(n) time solution.

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.
