1278. Palindrome Partitioning III

Leetcode Solutions

Dynamic Programming with Precomputed Palindrome Costs

  1. Initialize a 2D array changes to store the cost of converting substrings into palindromes.
  2. Fill the changes array by comparing characters at the two ends of each substring and moving inwards.
  3. Initialize a 2D DP array dp with dimensions k by n and set all values to INT_MAX.
  4. Set dp[0][r] for all r to changes[0][r] as the base case.
  5. Iterate over all possible splits kk from 1 to k-1.
  6. For each split kk, iterate over all possible right ends r of the substring.
  7. For each r, find the minimum cost by checking all possible left ends l of the last palindromic substring.
  8. Update dp[kk][r] with the minimum cost found.
  9. Return dp[k-1][n-1] as the final answer.
