Problem: Divide Array Into Increasing Sequences

Hard
40 min
Explore strategies to determine if a sorted array can be divided into one or more disjoint increasing subsequences, each at least length k. This lesson helps develop skills to track sequences and solve permutation-related problems in coding interviews using practical examples and exercises.

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.length103\leq 10^3

  • 11 \leq nums[i] 103\leq 10^3

  • The nums array is sorted in non-decreasing order.
