2811. Check if it is Possible to Split Array

Leetcode Solutions

Dynamic Programming with Memoization

  1. Initialize a memoization table dp with -1 for all entries.
  2. Calculate the prefix sum of the array for quick sum lookups.
  3. Define a recursive function solve that takes the current subarray bounds i and j, the original array nums, and the integer m.
  4. In solve, check if the current subarray can be split into valid subarrays according to the rules.
  5. If the subarray is a single element or the sum of the subarray is greater than or equal to m, return true.
  6. Otherwise, iterate over all possible split points k and recursively call solve on the two resulting subarrays.
  7. If both recursive calls return true, update the memoization table and return true.
  8. If no valid split is found, return false.
  9. Call solve with the full array bounds and return its result.
