Solution: Palindromic Substrings

Explore how to use dynamic programming techniques to count the number of palindromic substrings in a given string. Understand the construction and utilization of a lookup table that helps reduce redundant checks by storing previous results. Learn the method step-by-step, including handling base cases and extending the solution to longer substrings efficiently while balancing time and space complexities.

Statement

Given a string, s, return the number of palindromic substrings contained in it. A substring is a contiguous sequence of characters in a string. A palindrome is a phrase, word, or sequence that reads the same forward and backward.

Constraints:

  • 11 \leq s.length 1000 ...
