Solution: Divide Array Into Increasing Sequences

Understand how to decide if a sorted integer array can be partitioned into one or more increasing subsequences, each at least length k. Learn the frequency tracking method to efficiently assess this condition and implement a solution with O(n) time complexity. This lesson helps you apply data tracking patterns to solve array partition problems in coding interviews.

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 ...
