// This solution finds the Longest Palindromic Substring in a given string using Dynamic Programming. // A 2D boolean DP table tracks whether substrings are palindromes. // Single characters and equal ...

LeetCode’s Java ecosystem is evolving beyond mere algorithmic correctness, with a growing emphasis on code quality metrics such as readability, maintainability, and performance profiling.

// Time Complexity: O(n²) (due to substring creation and window reset) } else if (right == s.length() - 1 && !(map.containsKey(s.substring(left, right + 1)))) { map ...
