Solution: Divide Array Into Increasing Sequences

Explore how to solve the problem of dividing a sorted integer array into increasing subsequences of at least length k. Understand how to track frequencies of elements to determine if such partitioning is possible, and implement an efficient O(n) time complexity solution that balances sequence length and element distribution.

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:

  • ...
