2369. Check if There is a Valid Partition For The Array

Leetcode Solutions

Bottom-Up Dynamic Programming Approach

  1. Initialize an array dp of length n + 1 with all false values, and set dp[0] to true.
  2. Iterate over the array nums using index i:
    • Calculate dp_index as i + 1.
    • If i > 0 and nums[i] == nums[i - 1], set dp[dp_index] to dp[dp_index] or dp[dp_index - 2].
    • If i > 1 and nums[i] == nums[i - 1] == nums[i - 2], set dp[dp_index] to dp[dp_index] or dp[dp_index - 3].
    • If i > 1 and nums[i] == nums[i - 1] + 1 and nums[i - 1] == nums[i - 2] + 1, set dp[dp_index] to dp[dp_index] or dp[dp_index - 3].
  3. After the iteration, return the value of dp[n].
